1-June-2016 V. Uzhinsky (hadr-string-diff-V10-02-04)
Fine tuning of G4DiffractiveExcitation.cc of FTFmodel has been done
to describe NA49 exp. data, especially, <Pt> on Xf.
28-May-2016 V. Uzhinsky (hadr-string-diff-V10-02-03)
- Various <Pt^2> for diffr. and non-diffr. interactions were introduced
in G4FTFModel.cc for NA49 and NA61/SHINE exp. data.
23-May-2016 V. Uzhinsky (hadr-string-diff-V10-02-02)
- Tunning of FTF model parameters has been done.
17-May-2016 V. Uzhinsky (hadr-string-diff-V10-02-01)
- FTF model was essential improved:
Smearing of Delta-isobar mass was introduced;
Delta-isobars are now treated as a kinetic track;
Parameterisation the quark exchange process with excitation is improved also.
Na61/SHINE exp. data on Pi+, Pi-, K+, K- and protons in PP interactions at
20, 31, 40, 80 and 158 GeV/c are described. The ratio of <Strane Q>/<Normal Q>
in PP interactions is reproduced. The kink in AA interactions does not described.
5-May-2016 V. Uzhinsky (hadr-string-diff-V10-02-00)
- A bug was fixed in G4FTFModel for nucleus-nucleus interactions
if ( G4UniformRand() <
( 1.0 - target->GetSoftCollisionCount() / MaxNumOfInelCollisions ) * // Uzhi March 2015
( 1.0 - projectile->GetSoftCollisionCount() / MaxNumOfInelCollisions ) ) {
There are also some improvements in sampling of kinematical variables.
- G4FTFAnnihilation was improved. Now the code create Pi0, Eta and Eta_prime.
13-Aug-2015 A. Ribon (hadr-string-diff-V10-01-14)
- G4FTFModel and G4DiffractiveExcitation : Coverity fixes.

6-June-2016 V. Uzhinsky (had-hadronization-V10-02-05)
Re-tag of previouse tag. Compilation warning is erased.
4-June-2016 V. Uzhinsky (had-hadronization-V10-02-04)
A solution of the baryon puzzle of NA49 data has been found! <Pt>
of baryons 1/2 at a string fragmentation is setting up at 435 MeV/c,
and <Pt> for barion 3/2 production - 900 MeV/c.
1-June-2016 V. Uzhinsky (had-hadronization-V10-02-03)
Fine tuning of G4LundStringFragmentation.cc. <Pt> of mesons created at
quark fragmentation is decreased. <Pt> of baryons created at quark and
diquark is increased. Fragmentation functions of qq-> B(1/2) and B(3/2)
are implemented correctly.
28-May-2016 V. Uzhinsky (had-hadronization-V10-02-02)
<Pt^2> is increased in 2 times in G4LundStringFragmentation.cc.
It is very important for a description of NA49 exp. data on
pp-interactions at 158 GeV/c, especially for xF and Pt distributions.
23-May-2016 V. Uzhinsky (had-hadronization-V10-02-01)
Di-quark fragmentation into baryons is improved in LUND
string fragmentation. Description of NA49 and NA61/SHINE
exp. data on p+p->p+X is improved.
12-May-2016 V. Uzhinsky (had-hadronization-V10-02-00)
- G4LundStringFragmentation.cc, the method SetMinimalStringMass was improved
which is important for Pbar P annihilation.
13-Aug-2015 A. Ribon (had-hadronization-V10-01-09)

G4QGSMSplitableHadron : fixed bug in the case of gamma projectile
with P_minus = 0.
04 December 2015 Alberto Ribon (hadr-qgsm-V10-02-00)
Resumed the tag hadr-qgsm-V10-01-14, i.e. the new QGS model.
The files that are changed are: G4QGSDiffractiveExcitation.hh,
G4QGSMSplitableHadron.hh, G4QGSModel.icc, G4QGSParticipants.hh,
G4QGSMSplitableHadron.cc, G4GammaParticipants.cc, G4QGSParticipants.cc,
G4SingleDiffractiveExcitation.cc, G4QGSDiffractiveExcitation.cc and
G4SPBaryon.cc .
26 October 2015 Alberto Ribon (hadr-qgsm-V10-01-16)
After bringing the QGS string formation as it was in G4 10.1 (and before)
in the previous tag, check of 'while' loops and deploy the
