17-Oct-2020 V.Ivanchenko (hadr-qgsm-V10-06-06)
- G4QGSParticipants - added protection for G4Exp (fixing outstanding
precision lost in gamma+proton interactions)
28-Jul-2020 A. Ribon (hadr-qgsm-V10-06-05)
- G4BaryonSplitter : removed inexisting in Geant4 excited hyperon states
(Sigma* and Xi*).
24-Jul-2020 A. Ribon (hadr-qgsm-V10-06-04)
- G4BaryonSplitter, G4SPBaryon : extension to charmed and bottom
baryons and anti-baryons.
- G4SingleDiffractiveExcitation, G4QGSDiffractiveExcitation,
G4QuarkExchange : in the ExciteParticipants method of these classe,
extension to charmed and bottom hadrons by assuming a minimum
projectile diffractive mass equal to the PDG mass plus 250 MeV;
in G4QuarkExchange, assumed also 50% for the probability of
projectile diffraction.
- G4Reggeons : in the constructor, replaced Omega_cc (PDG code 4432)
with Omega_c (PDG code 4332); added comments.
06-Jul-2020 A. Ribon (hadr-qgsm-V10-06-03)
- G4QGSParticipants : rolled back the change in the average
transverse momentum of partons in a hadron.
10-Jun-2020 A. Ribon (hadr-qgsm-V10-06-02)
- Improved treatment of antibaryon interactions in QGS
(made by Vladimir Uzhinsky):
1. G4QGSParticipants : the average transverse momentum of partons
in a hadron is set to zero (according to the study of transverse
momentum distributions of hadrons produced in hadronic
interactions, in particular the study of Xf - Pt correlations
presented by the NA49 Collaboration).
2. G4QuarkExchange : the reggeon exchanges are now treated as
annihilation and creation of quark-antiquark pairs (to reflect
in inelastic processes the non-vacuum reggeon exchanges present
in antiparticle-particle elastic scattering amplitudes).
Two, unrelated changes made by Vladimir Uzhinsky :
- G4QuarkExchange : improved treatment of antibaryon interactions in QGS.
The reggeon exchanges are now treated as annihilation and creation of
quark-antiquark pairs (to reflect in inelastic processes the non-vacuum
reggeon exchanges present in antiparticle-particle elastic scattering
amplitudes).
- G4QGSParticipants : the average transverse momentum of partons
in a hadron is set to zero (according to the study of transverse
momentum distributions of hadrons produced in hadronic
interactions, in particular the study of Xf - Pt correlations
presented by the NA49 Collaboration).
