| 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
|
|---|
