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