19-Nov-2019 A. Ribon (had-hadronization-V10-05-04)
- G4ExcitedStringDecay : protection in the sampling of resonance masses
against values below threshold.
- G4LundStringFragmentation, G4QGSMFragmentation : in the method SplitEandP,
added a check that a string can be converted to an existing hadron
(else a null momentum is returned).
14-Nov-2019 A. Ribon (had-hadronization-V10-05-03)
- G4VLongitudinalStringDecay : forgotten initialization of c-cbar and b-bbar
pair production for kinks or gluons.
07-Nov-2019 A. Ribon (had-hadronization-V10-05-02)
- Implementation, made by Vladimir Uzhinsky, of the fragmentation functions
of heavy (charm and bottom) quarks and diquarks for the QGS string
fragmentation, based on a review of the available theoretical papers.
- The same set of mixing meson parameters (for both scalar and vector
mesons), as defined in the base class G4VLongitudinalStringDecay, are
now used on both FTF and QGS.
- Minor changes and clean-up for the Lund string fragmentation.
06-Nov-2019 A. Ribon (had-hadronization-V10-05-01)
- Correction by Vladimir Uzhinsky in the Lund string fragmentation regarding
the search for final-state in the last string decay.
Note: this bug was responsible of both the bad hadronic showers and the
slow CPU performances observed in 10.5.ref10.
- Switch off the probability of charm and bottom hadron production
in both Lund and QGS string fragmentations.
Note: this is a temporary protection, to be removed after the release.
09-Oct-2019 A. Ribon (had-hadronization-V10-05-00)
- Extension, made by Vladimir Uzhinsky, of both Lund and QGS string
fragmentation to allow the possibility to have charm and/or bottom quarks
and diquarks in the strings. As a result of the hadronization of strings
having heavy (c, b) quarks, charmed and bottom hadrons can be produced:
only heavy mesons and baryons that can fly macroscopic distances are
considered as candidate final states.
(Note: this extension has required also to extend the list of diquarks
available in Geant4, to add those made with charm and bottom quarks
in the method G4ShortLivedConstructor::ConstructQuarks.)
- Unused class G4VKinkyStringDecay has been removed.
20-Nov-2018 A. Ribon (had-hadronization-V10-04-07)
- Corrected only the History file (no other changes).
