<!-- ============================================== -->
<H2>4. New Developments and Capabilities </H2>
<B>General</B>
<UL>
<LI>Introducing new optional (Beta) tasking system, based on PTL
(Parallel Tasking Library), dedicated run manager (G4TaskRunManager) and
factory (G4RunManagerFactory), enabling use of tasks for the event loop.
The tasking system is fully compatible with Intel TBB, which can be
selected if GEANT4_USE_TBB=ON is specified when configuring CMake. The
default behavior for tasking is to submit the tasks to an internal
thread-pool and task-queue.</LI>
<LI>Introduced general facilities based on GFlash implementation to facilitate
multiple hit (energy & position) creation from fast simulation models.</LI>
<LI>Updated SI constants, based on May 2019 redefinition of SI units.</LI>
<LI>Added G4Backtrace header for printing backtraces from raised signals.
Can be enabled by setting GEANT4_BUILD_BUILTIN_BACKTRACE option at
configuration.</LI>
<LI>New profiling settings for TiMemory which allow per-{run,event,track,step}
profiling when GEANT4_USE_TIMEMORY is enabled.</LI>
<LI>Extended CMake build system to support G4Py activation through
GEANT4_USE_PYTHON flag.</LI>
<LI>Simplified CMake builds to enable future modularisation of Geant4
libraries.</LI>
</UL>
<B>Analysis</B>
<UL>
<LI>Major upgrade of analysis module, including support for multiple files
and multiple output types in the same run; defeined new methods and
corresponding UI commands. The new functions are available through a new
G4GenericAnalysisManager class, and are demonstrated in the basic B5
example.</LI>
<LI>Enabled handling of automatic min/max axes values in case of log scale
in analysis tools.</LI>
</UL>
<B>Digitization, Hits &amp; Scoring</B>
<UL>
<LI>Added layered mass geometry option for the new "probe" scoring mesh.</LI>
<LI>Introducing G4VPrimitivePlotter allowing the user to extend a primitive
scorer; added G4VScoreHistFiller and G4TScoreHistFiller, allowing scorers
to fill histograms defined through Geant4 Analysis tools.</LI>
</UL>
<B>Geometry and Field</B>
<UL>
<LI>Improved speed for detection of volume overlaps either through
UI commands or at geometry construction.</LI>
<LI>New templated field classes for equation and selected steppers
to avoid virtual call for field and equation respectively.
Non-virtual calls are expected to provide a direct speedup.
In addition key methods are made inline to enable compilers to
seek extra speedup by embedding them to avoid any function call.</LI>
<LI>New class G4DriverReporter to print progress of field drivers.</LI>
<LI>Enabled "check-mode" for G4PropagatorInField and G4VIntersectionLocator.</LI>
<LI>Enabled use of whiteboard for logging/debugging in G4MultiLevelLocator,
if "check-mode" in navigation is being activated through UI command.</LI>
</UL>
<B>Materials</B>
<UL>
<LI>Added two new public methods to add elements to a material:
AddElementsByNumberOfAtoms(...) and AddElementByMassFraction(...).</LI>
<LI>Added a new method ConstPropertyExists() to G4MaterialPropertiesTable.
Added new methods to access/add properties with G4String and std::vector.</LI>
<LI>Added new properties for scintillation allowing 3 time constants and a
second wavelength shifter in the same material in G4MaterialPropertiesTable
and G4MaterialPropertiesIndex.</LI>
</UL>
<B>Electromagnetic physics</B>
<UL>
<LI>Added two extra sets of StepFunction parameters for light ions and generic
ions. Added corresponding UI commands allowing one to customise step
limitation for ions separately from step limits for electrons or hadrons.</LI>
<LI>Introducing thermal model of positronium decay to two gammas.
In this model, the positronium acquires a mean kinetic energy on formation,
which contributes to a small non-collinearity of the gammas, detectable and
significant in PET.</LI>
<LI>Added new EM model for polarized gamma elastic scattering.</LI>
<LI>New class for handling the numerical Differential Cross-Sections(DCS) for
Coulomb scattering of e-/e+, and added new model, implementing single
Coulomb scattering for e-/e+.</LI>
<LI>Added new classes and models for micro-dosimetry simulation.</LI>
<LI>Added new threshold for muon/hadron bremsstrahlung and e+e- pair production
allowing to stop a track when energy transfer exceeds the defined threshold
and makes a new vertex.</LI>
<LI>Added a model for gamma-ray elastic interactions, able to account for
molecular interference effects, by using database or user-custom form
factors.</LI>
<LI>Implemented three time constants for G4Scintillation, and allow multiple
time constants to work with scintillation by particle type.
Added second wavelength shifting process within the same material.</LI>
</UL>
<B>Hadronic physics</B>
<UL>
<LI>For charm and bottom hadron-nuclear (elastic and inelastic)
cross sections, the Glauber-Gribov approach has been extended to
cover heavy hadrons.
For final-state elastic nuclear scattering of charm and bottom
hadron projectiles, a simple treatment is utilized.
For final-state inelastic nuclear scattering of charm and bottom
hadron projectiles, both Geant4 string models (FTF and QGS) have
been extended to deal with charm and bottom quarks and diquarks
carried by the heavy projectile hadron, as well as with the
possibility of creating charm-anti_charm and bottom-anti_bottom
pairs from the vacuum during the string fragmentation phase.
Cascade models are currently not applicable for heavy hadrons and
string models cannot handle them properly at very low energies:
below 100 MeV a dummy model that returns as final state the
initial state unchanged is utilized.
The decays of secondary heavy hadrons - charm and bottom hadrons
created by inelastic nuclear interactions of primary hadrons -
cannot be pre-defined by Monte Carlo event generators, therefore
a very simple approach is currently used: one single, fully hadronic
decay is defined for each "long"-lived charm and bottom hadron,
with a simple multi-body phase-space treatment of the decay
kinematics. </LI>
<LI>For the evaluation of systematic errors due to uncertainties in
the Geant4 hadronic cross sections we recommend to scale up and
down the cross sections, independently for elastic and inelastic
interactions, and independently for different types of hadrons.
Currently, this is possible for the following three categories of
hadrons: nucleons (i.e. proton and neutron together), pions (i.e.
pion+ and pion- together), all the rest of hadrons (i.e. kaons,
hyperons, anti-baryons, light ions, light anti-ions, charm and
bottom hadrons all together).
New public methods of the singleton class G4HadronicParameters
allow to enable the scaling of these cross sections (disabled by
default), and to set the scaling factors (by default 1.0).
Here are some rough, practical suggestions on the scaling of the
cross sections: +/- 10% variation for nucleons and pions;
+/- 15-20% variation for kaons; +/- 20-30% variation for other
hadrons. Moreover, bigger variations might be considered at low
energies to account for the challenge of describing the shapes
of cross sections in the threshold and resonance region. </LI>
<LI>New utility class to access hadronic processes, allowing to customise
hadronic cross-sections per particle type.</LI>
<LI>New UI messenger for hadronic physics, currently used for controlling
verbosity level: the UI command <TT>/process/had/verbose 0</TT> allows
to switch off the print-out at initialization of hadronic processes,
models and cross-sections (similar to the existing command
<TT>/process/em/verbose 0</TT> to switch off the print-out of
electromagnetic physics information).</LI>
<LI>New UI command to change the default upper energy limit
(default: 100 TeV): <TT>/process/had/maxEnergy ...</TT></LI>
<LI>New G4PARTICLEXS-3.1 dataset provides accurate fusion cross-sections
based on data, more accurate inelastic cross-sections for neutrons,
protons, light ions, and gamma for the full energy range.</LI>
<LI>Replaced where possible the use of environmental variables in hadronic
models with appropriate UI commands.</LI>
<LI>A new low-energy gamma-nuclear final-state model,
<TT>G4LowEGammaNuclearModel</TT>, based on precompound de-excitation
and providing isomer production and gamma transitions, is used in
<TT>G4EmExtraPhysics</TT>.</LI>
<LI>Improved treatment of antibaryon interactions in QGS.</LI>
<LI>Added handling of lepto-nuclear interactions for anti_nu_e, nu_e,
anti_mu_nu and mu_nu.</LI>
<LI>A new coalescence model, useful in particular for Cosmic Ray applications,
has been introduced. By considering the list of secondaries produced by a
string model, it forms deuterons and antideuterons from, respectively,
proton-neutron and antiproton-antineutron pairs with close momenta.
By default, the coalescence model is disabled; it can be switched on
via the UI command <TT>/process/had/enableCRCoalescence true</TT>.</LI>
</UL>
<B>Physics Lists</B>
<UL>
<LI>Enabled charm and bottom hadronic physics in nearly all physics lists,
in particular those of interest for HEP.
(The main exceptions are the following physics lists:
<TT>QGSP_BIC, QGSP_BIC_HP, QGSP_BIC_AllHP</TT>.)
The QGS-based physics lists use, as for other hadrons, QGSP for
charm and bottom inelastic interactions above 12 GeV, whereas FTFP
is used below 25 GeV. The other, FTF-based physics lists, use FTFP
at all energies, with a simplified approach below 100 MeV.</LI>
<LI>New physics-list builder classes have been introduced to allow
alternative builders for anti_proton, anti_neutron, hyperons and
anti-hyperons nuclear interactions at high energies with QGSP.</LI>
<LI>QGS-based physics lists use now QGS for hyperons, anti-hyperons,
anti_proton and anti_neutron projectiles at energies above 12 GeV.</LI>
<LI>Physics lists that include <TT>G4EmExtraPhysics</TT> use the new
low-energy gamma-nuclear model (<TT>G4LowEGammaNuclearModel</TT>)
below 200 MeV (while Bertini cascade is used above 199 MeV up to 6 GeV,
and QGSP above 3 GeV). The use of this model, its energy threshold and
the alternative cross section <TT>G4GammaNuclearXS</TT> can be
configured.</LI>
<LI>Extended EM physics-list configurator interface allowing application of
extra configuration on top of any available DNA constructor.</LI>
<LI>Cleanup destruction of physics processes at the end of job.
Reviewed ownership/deletion of physics models at the end of the run.</LI>
</UL>
<B>Visualization and Interfaces</B>
<UL>
<LI>Introduced new alpha-version of a Qt3D visualization driver, based
on native Qt rendering.</LI>
<LI>Added support for Open Inventor Qt visualisation driver to be built and
used in applications. The OpenInventor module can be built with either
the OIQt driver, or with the OIX/OIXE drivers, but not with both.
Enabled use of OIQt viewer with Qt UI.</LI>
</UL>
<B>Examples</B>
<UL>

simulating inelastic hadron-nuclear interactions.</LI>
<LI>New extended example demonstrating how to create multiple energy deposits
from the fast simulation model.</LI>

<LI>Implemented three time constants for G4Scintillation, and allow
multiple time constants to work with scintillation by particle type.
The existing material property names have FAST and SLOW in them, like
FASTTIMECONSTANT. This doesn't generalize well. Also YIELDRATIO as a
single value doesn't generalize to three time constants. Proposal is
to create new names SCINTILLATIONTIMECONSTANT1/2/3 and the same for
other parameters. The existing names are kept for backwards
compatibility, with the idea to remove them in the next major release.
There is a flag in G4Scintillation, with messenger command in the
OpticalPhysics list, to use the new method:
/process/optical/scintillation/setEnhancedTimeConstants true.
Results are unchanged if using same values.

SCINTILLATIONYIELD1) when only one scintillation channel is present.

<UL>
<LI>New class G4DriverReporter to print progress of drivers.</LI>
<LI>New templated classes to avoid virtual calls for field, equation,
steppers (from Google Summer of Code 2014 project): equation of motion
is now templated on the field type; steppers are templated on the type
of equation and the number of integration variables.
These classes can be combined also with the templated drivers to avoid
virtual calls in all the levels up to the chord finder's call to
the integration driver. </LI>
<LI>The default integration method for field propagation in a pure magnetic
field is changed. The constructor of G4ChordFinder by default uses the
new templated stepper G4TDormandPrince45 in place of
G4DormandPrince745.</LI>
<LI>The types of templated steppers currently available include
the efficient, embedded Runge-Kutta intermediate order steppers:
<UL>
<LI>G4TDormandPrince45: based on G4DormandPrince745, embedded
5<SUP>th</SUP> order; the default.</LI>
<LI>G4TCashKarpRKF45: based on G4CashKarpRKF45, 5<SUP>th</SUP> order;
first embedded RK.</LI>
</UL>
These are the most advanced templated steppers.
G4TDormandPrince45 provides an endpoint derivative (FSAL) and can be
used with interpolation.</LI>
<LI>The second type of templated steppers are non-embedded of 4<SUP>th</SUP>
and 3<SUP>rd</SUP> order:
<UL>
<LI>G4TClassicalRK4: based on G4ClassicalRK4, 4<SUP>th</SUP> order;
robust and the old default;</LI>
<LI>G4TSimpleHeum: based on G4SimpleHeum, 3<SUP>rd</SUP> order; a
lower order alternative;</LI>
</UL>
which break up a step into half steps to estimate error, meaning
they need several additional field evaluation calls than embedded
steppers of the same order.
The reliability of their error estimation has different properties; so
it may be more robust in some cases.
Primarily for comparison and cross-checking of results.</LI>
<LI>The final available type of low order templated steppers are very low
order:
<UL>
<LI>G4TSimpleRunge: based on G4SimpleRunge, 2<SUP>nd</SUP> order;</LI>
<LI>G4TExplicitEuler: based on G4ExplicitEuler, 1<SUP>st</SUP> order,
lowest order (the simplest checks only).</LI>
</UL>
only for tests or specialised uses.</LI>
<LI>Additional intermediate and higher-order steppers are not yet
available in templated form.</LI>
<LI>Adapted templated G4TDormandPrince45 for use with G4InterpolationDriver.
For a stepper to be used with this, it must implement the method
GetSpecificEquation().
Templated steppers must provide a return type which is the exact
equation type of the template.</LI>
<LI>Experimental versions of fields with inline methods (G4TUniformMagField
and G4TQuadrupoleMagField) demonstrate how the field evaluation
GetFieldValue() can also be inlined. Meant for use if the evaluation is
simple -- and to be avoided if it is complex when inlining it could
increase the code size significantly. </LI>
<LI>Configured G4ChordFinder to use templated G4TDormandPrince45 as the
default stepper for magnetic fields (when one is not chosen explicitly
by the application). Speed improvement is observed in benchmarks.
Note: currently it uses the simpler G4InterpolationDriver
in place of a customised G4BFieldIntegrationDriver which
multiplexed an interpolation driver for short steps with a
helix-based driver for long steps.
Applications with many <TT>large-angle</TT> steps in magnetic field may
perform more reliably and faster by restoring the use of the customised
driver - e.g. by using the G4ChordFinder constructor with <TT>nullptr</TT>
as third argument and fourth argument <TT>stepperDriverId=4</TT>.</LI>
<LI>G4VIntegrationDriver and dependent driver classes: added new virtual
method StreamInfo(), and used it to implement their operator<<().</LI>
<LI>G4MagInt_Driver: fixed max iterations & clarified that its method
ComputeNewStepSize() does not (yet) respect maximum reduction factor
(0.1); this is to enable comparisons with new G4IntegrationDriver<>
implementation.</LI>
<LI>G4OldMagIntDriver maintains all old behaviour of G4MagInt_Driver.</LI>

<LI>Improved treatment of antibaryon interactions in QGS.
In G4QGSMFragmentation, corrected the treatment of low-mass
diquark-antidiquark strings. In addition to this, introduced the Mt
distribution of produced hadrons.
In G4VLongitudinalStringDecay, introduced in SetMinimalStringMass()
a check that the strings are of allowed type: quark-antiquark,
diquark-antidiquark, quark-diquark and antiquark-antidiquark.
Introduced also for diquark-antidiquark strings a special algorithm
(already present for the other types of allowed strings) for treating
low-mass strings with masses below known hadrons.</LI>
<LI>Improved agreement of FTF simulations with NA49 experimental data (on
Pt-Xf correlations for various particles produced in pp interactions at

<LI>In G4QuarkExchange, the reggeon exchanges are now treated as
annihilation and creation of quark-antiquark pairs (to reflect in
inelastic processes the non-vacuum reggeon exchanges present in
antiparticle-particle elastic scattering amplitudes).</LI>
<LI>G4VLongitudinalStringDecay, G4LundStringFragmentation,
G4ExcitedStringDecay: inherit from G4HadronicInteraction; destruction
of these models at the end of run is now done by the hadron model
store; removed implementations of private operators.</LI>
<LI>G4VLongitudinalStringDecay: in the method SetMinMasses(), set the
constituent masses of charm and bottom quarks; introduced also a new
pre-processor option for debugging heavy hadrons, switched off by

comments.</LI>
<LI>G4VStringFragmentation: use inheritance from G4HadronicInteraction;

<LI>G4SPBaryonTable: changed return type of the method 'length()' from

<LI>G4FTFModel: attempt to fix a crash rarely observed in pion+proton

cleaned-up sampling of Pt for residual nucleons (limit argument for
G4Exp to 200 instead of 1e+9). Extended debug printout; use
pre-increment instead of post-increment in loops; removed commented

<LI>G4DiffractiveExcitation: extended to handle heavy (charm and bottom)

heavy hadrons, switched off by default. Added protection against
inexisting excited hyperon states (Sigma* and Xi*).

quark-diquark in the method CreateStrings().
Additional code improvements.</LI>
<LI>G4FTFAnnihilation: removed useless check against inexisting excited
hyperon states. Added initialization of 2-dimensional arrays as
suggested by Coverity. Used consistently pre-increment instead of
post-increment.</LI>
<LI>G4FTFParameters: extended FTF configuration interface to include
parameters of quark exchange with and without excitation, for
baryon and pion projectiles.</LI>
<LI>G4LundStringFragmentation, G4QGSMFragmentation: if the flag for heavy
(charmed and bottom) hadrons is enabled, then non-zero probabilities
for c-cbar and b-bbar creation from the vacuum are set, allowing
charmed and bottom hadrons to be created during the string fragmentation
of ordinary (i.e. not heavy) projectile hadron nuclear reactions.</LI>
<LI>G4LundStringFragmentation: extension to charm and bottom quarks of the
methods Quark_AntiQuark_lastSplitting() and Quark_Diquark_lastSplitting();
added protections in the method FragmentString() to avoid rare crashes
seen with heavy hadrons. Introduced a new parameter (as a class data
member), a kind of "temperature" for sampling the Pt of produced
hadrons; this parameter has been tuned for different fragmentation
processes. The string direction (one of string's properties, whose
value can be either +1 for projectile-like strings or -1 for target-like
strings) is now treated correctly and used to invert the results of the
string fragmentation (in the string rest frame) when the string
direction is -1.</LI>
<LI>G4HadronBuilder: fixed condition in the method Barion() to take into
account the extension to charm and bottom quarks; moreover, for both
Meson() and Barion() methods, we have to force by hand that the heavy
hadron produced by the string fragmentation is one of the few available
in Geant4 (in particular, all heavy hadron resonances are transformed
into close heavy hadron ground states). Introduced also a new
pre-processor option for debugging heavy hadrons, switched off by
default.</LI>
<LI>G4ExcitedStringDecay: added protection in the FragmentStrings() method
to avoid rare crashes seen with heavy hadrons.</LI>
<LI>G4BaryonSplitter, G4SPBaryon: extension to charmed and bottom

<LI>G4SingleDiffractiveExcitation, G4QGSDiffractiveExcitation,
G4QuarkExchange: in ExciteParticipants() method of these classes,
extension to charmed and bottom hadrons by assuming a minimum
projectile diffractive mass equal to the PDG mass plus 250 MeV;
in G4QuarkExchange, assumed also 50% for the probability of projectile
diffraction.</LI>
<LI>G4Reggeons: in the constructor, replaced Omega_cc (PDG code #4432)

<LI>G4QMDReaction: added code in ApplyYourself() to get the cross section

<LI>G4TheoFSGenerator: introduced temporarily dummy treatment of heavy

Cascade models are currently not applicable for heavy hadrons and
string models cannot handle them properly at very low energies, so we
return as final state the initial state unchanged.
Note that, for most applications, this is a safe simplification, giving
that the nearly all slowly moving charm and bottom hadrons decay before

<LI>Added new parameter to DetectorConstruction constructor; added
instance of DetectorManager in main().</LI>
<LI>DetectorConstruction: defined private methods to construct a
specific type of detector ("Silicon", "Diamond", and "MicroDiamond");
added detectorType private string to store the name of the one in
use; rewrote Construct() so that it calls the specific method of
the selected detector type; moved the previous diamond detector
geometry to ConstructDiamondDetector() and added new possible
geometries (silicon and microdiamond).</LI>
<LI>DetectorMessenger: created file in order to switch detector type.</LI>
<LI>New macro geometry.mac, to select a specific detector at runtime
(by default, all options are commented out).
Added a line in vis.mac to execute geometry.mac before launching
the GUI (at which point it wouldn't be possible to change the
geometry anymore). Added a line in run.mac to execute geometry.mac.</LI>
