13-Aug-2015 A. Ribon (hadr-string-diff-V10-01-14)
- G4FTFModel and G4DiffractiveExcitation : Coverity fixes.
10-Aug-2015 A. Ribon (hadr-string-diff-V10-01-13)
- G4FTFModel, G4FTFParticipants, G4FTFAnnihilation, G4ElasticHNScattering,
G4DiffractiveExcitation and G4DiffractiveSplitableHadron : checking of
'while' loops.
05-Aug-2015 A. Ribon (hadr-string-diff-V10-01-12)
- G4FTFParameters, G4FTFModel, G4FTFAnnihilation, G4DiffractiveExcitation
and G4ElasticHNScattering: replaced std::exp, std::log and std::pow
with the faster G4Exp, G4Log and G4Pow, respectively.
This changes the random number sequence.
13-Jul-2015 A. Dotti (hadr-string-diff-V10-01-11)
- Fixing coverity issues #14434, 20328
25-Jun-2015 A. Ribon (hadr-string-diff-V10-01-10)
- G4FTFParameters : fixed Valgrind error of uninitialized variables.
29-May-2015 V. Uzhinsky (hadr-string-diff-V10-01-09)
- G4FTFModel : Elastic hN scattering is protected.
28-May-2015 A. Ribon (hadr-string-diff-V10-01-08)
- G4FTFModel : fixed energy non-conservation in nucleus-nucleus interactions
in the method SamplingNucleonKinematics.
25-May-2015 V. Uzhinsky (hadr-string-diff-V10-01-07)
A correct coupling of FTF and BIC is created. Energy-momentum is conserved.
24-May-2015 V. Uzhinsky (hadr-string-diff-V10-01-06)
Bug is fixed in G4FTFModel::SamplingNucleonKinematics for
hadron-nucleon interactions.
22-May-2015 V. Uzhinsky (hadr-string-diff-V10-01-05)
Sampling of nucleon momenta after the reggeon cascading is improved in
G4bool G4FTFModel::SamplingNucleonKinematics.
20-May-2015 V. Uzhinsky (hadr-string-diff-V10-01-04)
G4FTFModel.cc A model description was added.
18-May-2015 V. Uzhinsky (hadr-string-diff-V10-01-03)
G4FTFModel.cc
LowEnergyLimit = 2000.0*MeV -> LowEnergyLimit = 1000.0*MeV;
G4FTFParameters.cc
A bug at Xnn calculations found by Alberto is fixed. The bug gives Xin=0 for projectile
nucleons in Nucl-Nucl interactions.
New methods - Set/Get CofNuclearDestructionPr(), for projectile nucleus were introduced,
according to last studies that Reggeon cascading depends on nuclear mass number.
22-Apr-2015 A. Ribon (hadr-string-diff-V10-01-02)
- G4FTFParticipants : added a new method to clean up the member vector.
- G4FTFModel : using the above new method to release the memory allocated
in GetStrings().
7-April-2015 V. Uzhinsky (hadr-string-diff-V10-01-01)
G4FTFModel.cc
LowEnergyLimit = 2000.0*MeV -> LowEnergyLimit = 1000.0*MeV;
A smearing of the excitation energy associated with an involved nucleon is introduced.
Look for // Uzhi April 2015
G4FTFParameters.cc
Evarage e* per wounded nucleon was to set 40 MeV for all interactions after analysis of
ITEP and Leray exp. data.
27-Mar-2015 A. Ribon (hadr-string-diff-V10-01-00)
- G4FTFParameters : tuning to improve the description of evaporated neutrons
27-Nov-2014 V. Uzhinsky (hadr-string-diff-V10-00-15)
- Charge non-conservation is erased for meson-nucleus interactions
in G4Diffractive Excitation. It was caused by quark exchange.
