History file for hadronic/models/parton_string/qgsm directory
-------------------------------------------------------------
This file should be used to summarize modifications introduced in the
code and to keep track of all tags.
---------------------------------------------------------------
* Please list in reverse chronological order (last date on top)
---------------------------------------------------------------
26 October 2015 Alberto Ribon (hadr-qgsm-V10-01-16)
After bringing the QGS string formation as it was in G4 10.1 (and before)
in the previous tag, check of 'while' loops and deploy the
fast math functions (G4Exp, G4Log and G4Pow).
23 October 2015 Alberto Ribon (hadr-qgsm-V10-01-15)
Reversed (temporarily, just for the coming release G4 10.2) the
improvements made after 10.1.ref05, in such a way to leave the
QGS string formation as it was in G4 10.1 (and before).
The files that are changed are: G4QGSDiffractiveExcitation.hh,
G4QGSMSplitableHadron.hh, G4QGSModel.icc, G4QGSParticipants.hh,
G4QGSMSplitableHadron.cc, G4GammaParticipants.cc, G4QGSParticipants.cc,
G4SingleDiffractiveExcitation.cc, G4QGSDiffractiveExcitation.cc and
G4SPBaryon.cc .
After the release G4 10.2, the tag hadr-qgsm-V10-01-14 will be resumed.
13 August 2015 Alberto Ribon (hadr-qgsm-V10-01-14)
G4GammaParticipants, G4QGSParticipants : Coverity fixes.
07 August 2015 Alberto Ribon (hadr-qgsm-V10-01-13)
G4QGSModel, G4QGSMSplitableHadron, G4GammaParticipants, G4QGSParticipants,
G4SingleDiffractiveExcitation and G4QGSDiffractiveExcitation :
checking of 'while' loops.
05 August 2015 Alberto Ribon (hadr-qgsm-V10-01-12)
G4ASCCrossSection, G4QGSMSplitableHadron, G4QGSParticipants,
G4SingleDiffractiveExcitation and G4QGSDiffractiveExcitation:
replaced std::exp, std::log and std::pow with the faster
G4Exp, G4Log and G4Pow, respectively.
This changes the random number sequence.
12 June 2015 Alberto Ribon (hadr-qgsm-V10-01-11)
G4QGSParticipants: fixed a memory leak.
10 June 2015 Alberto Ribon (hadr-qgsm-V10-01-10)
G4QGSParticipants: commented one forgotten debugging print out statement.
4 June 2015 V. Uzhinsky (hadr-qgsm-V10-01-09)
G4QGSMSplitableHadron - iterator deque used as data member is
replaced by "unsigned int" data member. I hope it avoid segmentation
fault.
28 May 2015 Alberto Ribon (hadr-qgsm-V10-01-08)
G4QGSParticipants : improved the kinematics treatment in the method
SamplingNucleonKinematics.
27 May 2015 Vladimir Uzhinsky (hadr-qgsm-V10-01-07)
A bug lead to Segmentation fault is erased. It was connected with G4Nucleus -> GetNextNucleon()
used at gamma projectile which gave pointer outside nucleon vector.
After that wrong counting of see parton pairs was obtained, and at iteration of the partons
GetNextParton went out of the parton vector.
The changes are:
G4VSplitableHadron* G4GammaParticipants::SelectInteractions
theNucleus->StartLoop();
G4Nucleon * pNucleon =0; // theNucleus->GetNextNucleon(); // Uzhi 27.05.2015
while( (pNucleon = theNucleus->GetNextNucleon()) )
....
22 May 2015 Vladimir Uzhinsky (hadr-qgsm-V10-01-06)
A bug is fixed for gamma projectile. In G4QGSParticipants::BuildInteractions
for gamma instead of GetList SelectInteractions(theProjectile) is called.
21 May 2015 Vladimir Uzhinsky (hadr-qgsm-V10-01-05)
Class G4GammaParticipants is adjusted to new QGSM.
20 May 2015 Vladimir Uzhinsky (hadr-qgsm-V10-01-04)
A bug is fixed in G4QGSParticipants for gamma projectile.
19 May 2015 Vladimir Uzhinsky (hadr-qgsm-V10-01-03)
To avoid double deletion erasing of TheInvolvedNucleonsOfTarget and
TheInvolvedNucleonsOfProjectile was closed in G4QGSParticipants::~G4QGSParticipants().
15 May 2015 Vladimir Uzhinsky (hadr-qgsm-V10-01-02)
A bug was erased in G4SPBaryon.cc: setting of Delta0 isobar splitting
into quark and diquark was wring.
Energy-momentum conservation was improved, especially in the case when
diffraction interactions happend.
12 May 2015 Vladimir Uzhinsky (hadr-qgsm-V10-01-01)
Bug is erased with double delition of splitable hadrons.
30 April 2015 Vladimir Uzhinsky (hadr-qgsm-V10-01-00)
- Essential improvement of QGSM:
Reggeon cascading was implemented.
"Fermi motion" connected with the reggeon cascading was implemented.
New algorithm of parton kinematical properties determination was implemented.
Calculation of residual nucleus properties was implemented.
Most of the changes were made in G4QGSParticipants.cc
02 May 2013 Alberto Ribon (hadr-qgsm-V09-06-00)
--------------------------------------------------
- For thread safety, replaced CLHEP::RandFlat with G4RandFlat in
G4QGSMSplitableHadron.cc.
20 November 2012 V. Uzhinsky (hadr-qgsm-V09-05-04)
--------------------------------------------------
- An interface for a manipulation with nucleus-nucleus interactions was
introduced, especially for treating remnants of projectile nuclei.
27 September 2012, Gabriele Cosmo
--------------------------------------------------
- Explicitly use inclusion of headers for system of units and physical
constants, in plan to remove implicit inclusion from globals.hh.
17 June 2012, Gunter Folger (hadr-qgsm-V09-05-03)
--------------------------------------------------
- Fixes for coverity in G4QGSModel concerning copy ctor and operator = .
12 June 2012, Gunter Folger (hadr-qgsm-V09-05-02)
--------------------------------------------------
- Correct shadowing warnings
31 May 2012, Gunter Folger (hadr-qgsm-V09-05-01)
--------------------------------------------------
- Improve indentation;
- make copy ctor, =, ==, != operators private without implementation
25 May 2012, Gunter Folger (hadr-qgsm-V09-05-00)
--------------------------------------------------
- Add ModelDescription() to QGS
5 Aug 2011, M. Kelsey (hadr-qgsm-V09-04-04)
-----------------------------------------------------
- G4GammaParticipants.cc: Follow change in return value of
G4V3DNucleus::GetNucleons(), use const_cast<> to allow setting Hit().
- G4QGSParticipants.hh: Add G4V3DNucleus.hh (should move implementations to
.cc file).
Requires consistent changes in other packages:
hadr-modman-V09-04-01
hadr-mod-util-V09-04-02
had-partonstring-mgt-V09-04-01
hadr-qgsm-V09-04-04
had-theo-HE-V09-04-01
14 Jul 2011, G.Folger (hadr-qgsm-V09-04-03)
-----------------------------------------------------
- Fix coverity warnings in G4QGSParticipants.cc and G4SPBaryon.cc
(none was a real problem)
01 Jun 2011, G.Folger (hadr-qgsm-V09-04-02)
-----------------------------------------------------
- G4QGSParticipants: reduce energy of participant nucleons by binding energy.
This increases excitation energy, as calculated by initial-final. Without
this, excitation E often is close to 0, or negative.
01 Jun 2011, G.Folger (hadr-qgsm-V09-04-01)
-----------------------------------------------------
- Fix compilation warnings, gcc4.6, on alost unused variables. Move
"debug" variables into #ifdef
17 Mar 2011, G.Folger (hadr-qgsm-V09-04-00)
-----------------------------------------------------
- set limits for E/p checking
8 Sep 2010, G.Folger (hadr-qgsm-V09-03-01)
-----------------------------------------------------
- G4QGSModel.icc: use integer (A,Z) interface of nucleus
12-Mar-2010, G.Folger (hadr-qgsm-V09-03-00)
- remove G4PartonStringAnnihilator.{hh,cc} not used anywhere
19 May 2009, G.Folger (hadr-qgsm-V09-02-02)
-----------------------------------------------------
- fix in G4SPBaryon: for antibaryon, a diquark & quark was given instead of
anti-diquark & antiquark; note the reverse order, too.
Fixes problems with incident anti baryons, e.g. antiproton, manifesting
in problems with forming hadrons.
29 Apr 2009 m. Kosov (hadr-qgsm-V09-02-01)
------------------------------------------------
Very important bug fix in G4QGSParticipants.cc to let QGSC working from E=0
Added by GF (19-May-09):
- this very important "bug" fix modifies G4G4QGSParticipants.cc and
G4GammaParticipants.cc:
changing the value of Threshold from 0.45 GeV to 0.GeV,
and disables an Exception if s < sqr(total mass + Threshold)
15 Sep 2008 G.Folger (hadr-qgsm-V09-01-01)
------------------------------------------------
- Fix for bug found on windows in G4QGSParticipants.cc, bug 1018:
decrement of iterator fails, improve logic to not decrement.
31 Mar 2008 Dennis Wright (hadr-qgsm-V09-01-00)
-----------------------------------------------
- fix gcc-4.3 compiler warnings at lines 293, 395 of G4QGSMSplittableHadron.cc
24 Apr 2007 Gunter Folger (hadr-qgsm-V08-02-02)
------------------------------------------------
- merge in change done by ftf dev; ie. in G4QGSParticipants, theDiffExcitaton
is constructed with default arguments.
25 Jan 2007 Gunter Folger (hadr-qgsm-V08-02-01)
------------------------------------------------
- G4SoftStringBuilder.cc: Correct typo in #ifdef
24 Jan 2007 Gunter Folger (hadr-qgsm-V08-02-00)
------------------------------------------------
- Correct E-p non-conservation in QGS. In 4QGSMSplitableHadron.cc the smaller
of the lightcone momenta Q+/Q- was ignored.
- G4QGSMSplitableHadron correct divide by 0 in SampleX()
- Add debugging output to several classes
30 Nov 2005 Gabriele Cosmo (hadr-qgsm-V07-01-00)
