---------------------------------------------------------------
27-Sep-2012, G.Cosmo
- Explicitly use inclusion of headers for system of units and physical
constants, in plan to remove implicit inclusion from globals.hh.
13-Aug-2012, A.Ribon (had-hadronization-V09-05-06)
- Fixed compilation error in G4ExcitedStringDecay.cc when the constructor
of the Lorentz vector is made explicit.
25-Jul-2012, G.Folger (had-hadronization-V09-05-05)
- Fixes for coverity in G4LundStringFragmentation.cc .
17-Jul-2012, G.Folger (had-hadronization-V09-05-04)
- fixes for coverity in G4FragmentingString and G4VLongitudinalStringDecay
12-Jun-2012, G.Folger (had-hadronization-V09-05-03)
- fix warnings on shadowed variables, affected G4LundStringFragmentation.cc
25-May-2012, G.Folger (had-hadronization-V09-05-02)
- make copy ctor, =, == , and != operators private without implementation,
fixing coverity warnings
21 May 2012, Vladimir Uzhinsky (had-hadronization-V09-05-01)
- Probabilities of s-sbar quark pairs and qq-qqbar diquark pairs
are changed in G4LundStringFragmentation for a description of
the NA49 collaboration data.
12-Apr-2012, G.Folger (had-hadronization-V09-05-00)
- Changes in debugging information in src/G4ExcitedStringDecay.cc
08 Nov 2011, Alberto Ribon (had-hadronization-V09-04-03)
- Tagged the improvements in the code structure of the class
G4LundStringFragmentation. Results remain exactly the same
as before these code improvements.
08 Nov 2011, Alberto Ribon, svn rev 54374
- Factorized the method G4LundStringFragmentation::FragmentString
to make the code easier to understand and maintain.
Also put at the end of the .cc file all newly added methods.
04 Nov 2011, Alberto Ribon, svn rev 54124
- Factorized the method G4LundStringFragmentation::SplitLast
to make the code easier to understand and maintain.
02 Nov 2011, Alberto Ribon, svn rev 53955
- Made public the virtual method G4LundStringFragmentation::FragmentString.
Clean up also old commented lines in two G4LundStringFragmentation
methods: StopFragmenting and FragmentString.
1 Nov 2011, Gunter Folger, svn rev 53895
- G4LundStringFragmentation: simplify GetLightConeZ()
29 Sep 2011, Gunter Folger, svn rev 52604
- G4LundStringFragmentation: Cleanup indentation
19 Jul 2011, Gunter Folger (had-hadronization-V09-04-02)
- Correct mistake in tagging made for had-hadronization-V09-04-00/01
19 Jul 2011, Gunter Folger bad tag (had-hadronization-V09-04-00)
- Address coverity warnings.
One outstanding warning in G4LundStringFragmentation::Splitlast().
3 Nov 2010, Gunter Folger (had-hadronization-V09-03-02)
- fix minor coverity warnings in G4HadronBuilder
22-September-2010 V. Uzhinsky (had-hadronization-V09-03-01)
--------------------------------------------------------------
- Warning messages are erased in G4LundStringFragmentation.cc
20-September-2010 V. Uzhinsky
------------------------------
- Phase space restrictions are introduced at small mass string
fragmentation.
5-August-2010 V. Uzhinsky
--------------------------
- Small re-organization is done in G4ExcitedStringDecay.hh. Inline
methods were moved to G4ExcitedStringDecay.cc.
- An action is introduced in FragmentStrings. It acts when
EnergyAndMomentumCorrector can not be done due to large sum masses
of produced hadrons. This led to energy-momentum violation. Now
string fragmentation is repeted 100 times in a bad case.
21-June-2010 V. Uzhinsky (had-hadronization-V09-03-00)
--------------------------------------------------------------
- Lund string fragmentation is improved. The inselfconsistency
between LightFragmentationTest and Lund fragmentation is erased.
Energy conservation in FTF is recovered.
6-December-2010 V. Uzhinsky, (had-hadronization-V09-02-04)
--------------------------------------------------------------
- Lund string fragm. improved, start fragmentation.
17-July-2009 V. Uzhinsky (had-hadronization-V09-02-03)
--------------------------------------------------------------
- Some small optimization are done.
9-July-2009 V. Uzhinsky (had-hadronization-V09-02-02)
--------------------------------------------------------------
- Bug was fixed in G4VLongitudinalStringDecay.cc at calculation of
formation/creation time, c_light was inserted.
- String tension parameter was set to the usual value (1 GeV/fm) in
G4LundStringFragmentation.cc
22-May-2009 Gunter Folger (had-hadronization-V09-02-01)
--------------------------------------------------------------
- remove temporary workaround - fix is now in QGS
- change pt sampling in G4LundStringFragmentation to avoid near endless
loop; this should improve overall performance slightly.
Affected G4VLongitudinalStringDecay, where SampleQuarkPt() is
implemented; affected .hh and .cc for new optional argument of max Pt
to SampleQuarkPt()
18-May-2009 Gunter Folger (had-hadronization-V09-02-00)
---------------------------------------------------------------------
- reset formatting changes by MK with tags hadr-prtn-hadr-V09-02-xx
- temporary workaround for wrong PDG codes created on wrong input from QGS
when used for e.g. antiproton.
2-May 2007 Gunter Folger (had-hadronization-V08-02-03)
---------------------------------------------------------------------
- G4ExcitedStringDecay.hh: protect againt divide by 0 when KTsum1.e() is 0.
24-April 2007 Gunter Folger (had-hadronization-V08-02-02)
---------------------------------------------------------------------
- Seperate FTF and QGS fragmentation dir methods where V.Uzhinsky
modified the algorithm for FTF.
2-March 2007 Gunter Folger (had-hadronization-V08-02-01)
---------------------------------------------------------------------
- G4ExcitedStringDecay::EnergyAndMomentumCorrector no longer causes Exception
when no converging. Add more info when failing. Return correct status.
24-Jan 2007 Gunter Folger (had-hadronization-V08-02-00)
--------------------------------------------------------------
- G4ExcitedStringDecay::EnergyAndMomentumCorrector :
Correct bug which did stop correction even if not yet converged;
check on convergence must check that scale-1 is close to 0,
and not less than 0
26-May 2006 Gunter Folger
--------------------------------------------------------------
- Fix ( finally?) the charge check in G4HadronBuilder.cc
