Major revision of the QGS final-state model
Implemented Reggeon cascading and "Fermi motion";
New algorithm for the determination of the kinematical properties of partons;
Improved formation of the residual nucleus. Improved cross-sections of K-meson - nucleon interactions in QGS: Pomeron and two non-vacuum exchanges are taken into account.
Gamma-nucleon cross sections are also improved by tuning of parameters.
Improved string fragmentation ( G4QGSMFragmentation ): new algorithm for last string decay a-la Lund is implemented;
Tuning the parameters related to both string formation and string fragmentation to improve the description of thin-target data.
In all hadronic builders fixed use of data for neutron capture in HP physics-lists.
For FTF/QGS/INCLXX physics-lists builders, use Barashenkov-Glauber-Gribov inelastic cross-section for pions, avoiding to use Gheisha cross-sections for pion inelastic on Hydrogen target.
Both hadronic string models ( FTF and QGS ) describe generally better the thin-target data with respect to the previous versions. Moreover, the QGS model becomes competitive with the FTF model, for most thin-target observables for projectile kinetic energies above about 20 GeV.
CoulombScat was introduced by 10.04, 10.05 addresses an issue in G4eSingleCoulombScatteringModel:
G4eSingleCoulombScatteringModel : fixed calculation of scattering angle. Addressing problem report #2090.
In part contributed to differences in Geant4.10.4
Hadronic shower simulation: FTF and QGS models now give higher energy response and are consistently higher than comparative test-beam and collider data.
