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