[1347] | 18 | 3 Nov 2010, Gunter Folger (had-hadronization-V09-03-02) |
---|
| 19 | - fix minor coverity warnings in G4HadronBuilder |
---|
| 20 | |
---|
[1340] | 21 | 22-September-2010 V. Uzhinsky (had-hadronization-V09-03-01) |
---|
| 22 | -------------------------------------------------------------- |
---|
| 23 | - Warning messages are erased in G4LundStringFragmentation.cc |
---|
| 24 | |
---|
| 25 | 20-September-2010 V. Uzhinsky |
---|
| 26 | ------------------------------ |
---|
| 27 | - Phase space restrictions are introduced at small mass string |
---|
| 28 | fragmentation. |
---|
| 29 | |
---|
| 30 | 5-August-2010 V. Uzhinsky |
---|
| 31 | -------------------------- |
---|
| 32 | - Small re-organization is done in G4ExcitedStringDecay.hh. Inline |
---|
| 33 | methods were moved to G4ExcitedStringDecay.cc. |
---|
| 34 | |
---|
| 35 | - An action is introduced in FragmentStrings. It acts when |
---|
| 36 | EnergyAndMomentumCorrector can not be done due to large sum masses |
---|
| 37 | of produced hadrons. This led to energy-momentum violation. Now |
---|
| 38 | string fragmentation is repeted 100 times in a bad case. |
---|
| 39 | |
---|
[1337] | 40 | 21-June-2010 V. Uzhinsky (had-hadronization-V09-03-00) |
---|
| 41 | -------------------------------------------------------------- |
---|
| 42 | - Lund string fragmentation is improved. The inselfconsistency |
---|
| 43 | between LightFragmentationTest and Lund fragmentation is erased. |
---|
| 44 | Energy conservation in FTF is recovered. |
---|
| 45 | |
---|
| 46 | 6-December-2010 V. Uzhinsky, (had-hadronization-V09-02-04) |
---|
| 47 | -------------------------------------------------------------- |
---|
| 48 | - Lund string fragm. improved, start fragmentation. |
---|
| 49 | |
---|
| 50 | 17-July-2009 V. Uzhinsky (had-hadronization-V09-02-03) |
---|
| 51 | -------------------------------------------------------------- |
---|
| 52 | - Some small optimization are done. |
---|
| 53 | |
---|
[1196] | 54 | 9-July-2009 V. Uzhinsky (had-hadronization-V09-02-02) |
---|
[1337] | 55 | -------------------------------------------------------------- |
---|
[1196] | 56 | - Bug was fixed in G4VLongitudinalStringDecay.cc at calculation of |
---|
| 57 | formation/creation time, c_light was inserted. |
---|
| 58 | - String tension parameter was set to the usual value (1 GeV/fm) in |
---|
| 59 | G4LundStringFragmentation.cc |
---|
[819] | 60 | |
---|
[1337] | 61 | 22-May-2009 Gunter Folger (had-hadronization-V09-02-01) |
---|
[1196] | 62 | -------------------------------------------------------------- |
---|
[1055] | 63 | - remove temporary workaround - fix is now in QGS |
---|
| 64 | - change pt sampling in G4LundStringFragmentation to avoid near endless |
---|
| 65 | loop; this should improve overall performance slightly. |
---|
| 66 | Affected G4VLongitudinalStringDecay, where SampleQuarkPt() is |
---|
| 67 | implemented; affected .hh and .cc for new optional argument of max Pt |
---|
| 68 | to SampleQuarkPt() |
---|
| 69 | |
---|
| 70 | 18-May-2009 Gunter Folger (had-hadronization-V09-02-00) |
---|
| 71 | --------------------------------------------------------------------- |
---|
| 72 | - reset formatting changes by MK with tags hadr-prtn-hadr-V09-02-xx |
---|
| 73 | - temporary workaround for wrong PDG codes created on wrong input from QGS |
---|
[1337] | 74 | when used for e.g. antiproton. |
---|
[1055] | 75 | |
---|
[819] | 76 | 2-May 2007 Gunter Folger (had-hadronization-V08-02-03) |
---|
| 77 | --------------------------------------------------------------------- |
---|
[1337] | 78 | - G4ExcitedStringDecay.hh: protect againt divide by 0 when KTsum1.e() is 0. |
---|
[819] | 79 | |
---|
| 80 | 24-April 2007 Gunter Folger (had-hadronization-V08-02-02) |
---|
| 81 | --------------------------------------------------------------------- |
---|
[1337] | 82 | - Seperate FTF and QGS fragmentation dir methods where V.Uzhinsky |
---|
| 83 | modified the algorithm for FTF. |
---|
[819] | 84 | |
---|
[1337] | 85 | 2-March 2007 Gunter Folger (had-hadronization-V08-02-01) |
---|
[819] | 86 | --------------------------------------------------------------------- |
---|
| 87 | - G4ExcitedStringDecay::EnergyAndMomentumCorrector no longer causes Exception |
---|
[1337] | 88 | when no converging. Add more info when failing. Return correct status. |
---|
[819] | 89 | |
---|
[1337] | 90 | 24-Jan 2007 Gunter Folger (had-hadronization-V08-02-00) |
---|
| 91 | -------------------------------------------------------------- |
---|
| 92 | - G4ExcitedStringDecay::EnergyAndMomentumCorrector : |
---|
| 93 | Correct bug which did stop correction even if not yet converged; |
---|
| 94 | check on convergence must check that scale-1 is close to 0, |
---|
| 95 | and not less than 0 |
---|
[819] | 96 | |
---|
[1337] | 97 | 26-May 2006 Gunter Folger |
---|
| 98 | -------------------------------------------------------------- |
---|
| 99 | - Fix ( finally?) the charge check in G4HadronBuilder.cc |
---|
