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
|
