18 | 3 Nov 2010, Gunter Folger (had-hadronization-V09-03-02) |
---|
19 | - fix minor coverity warnings in G4HadronBuilder |
---|
20 | |
---|
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 | |
---|
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 | |
---|
54 | 9-July-2009 V. Uzhinsky (had-hadronization-V09-02-02) |
---|
55 | -------------------------------------------------------------- |
---|
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 |
---|
60 | |
---|
61 | 22-May-2009 Gunter Folger (had-hadronization-V09-02-01) |
---|
62 | -------------------------------------------------------------- |
---|
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 |
---|
74 | when used for e.g. antiproton. |
---|
75 | |
---|
76 | 2-May 2007 Gunter Folger (had-hadronization-V08-02-03) |
---|
77 | --------------------------------------------------------------------- |
---|
78 | - G4ExcitedStringDecay.hh: protect againt divide by 0 when KTsum1.e() is 0. |
---|
79 | |
---|
80 | 24-April 2007 Gunter Folger (had-hadronization-V08-02-02) |
---|
81 | --------------------------------------------------------------------- |
---|
82 | - Seperate FTF and QGS fragmentation dir methods where V.Uzhinsky |
---|
83 | modified the algorithm for FTF. |
---|
84 | |
---|
85 | 2-March 2007 Gunter Folger (had-hadronization-V08-02-01) |
---|
86 | --------------------------------------------------------------------- |
---|
87 | - G4ExcitedStringDecay::EnergyAndMomentumCorrector no longer causes Exception |
---|
88 | when no converging. Add more info when failing. Return correct status. |
---|
89 | |
---|
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 |
---|
96 | |
---|
97 | 26-May 2006 Gunter Folger |
---|
98 | -------------------------------------------------------------- |
---|
99 | - Fix ( finally?) the charge check in G4HadronBuilder.cc |
---|
