19 November 2009, Gunter Folger (hadr-prtn-V09-02-09)
|
|
- G4VParticipants.hh: use modified name of method to sort nucleons in G4V3DNucleus
|
|
|
|
29 October 2009, V. Uzhinsky (hadr-prtn-V09-02-08)
|
|
Warning meassage is erased in FTFmodel
|
|
-----------------------------------------------------
|
|
25 October 2009, V Uzhinsky (hadr-prtn-V09-02-07)
|
|
Excitation energy calculation was added in FTF.
|
|
-----------------------------------------------------
|
|
|
|
6 October 2009, V Uzhinsky (hadr-prtn-V09-02-06)
|
|
Compilation warning are erased in FTF.
|
|
|
|
-----------------------------------------------------
|
|
5 October 2009, V. Uzhinsky (hadr-prtn-V09-02-05)
|
|
FTFP with tuned parameters of nuclear de-excitation.
|
|
------------------------------------------------------
|
|
6 August 2009, V. Uzhinsky (hadr-prtn-V09-02-04)
|
|
A warning message at FTFmodel compilation connected with Xminus
|
|
initialisation was erased.
|
|
------------------------------------------------------
|
|
5 August 2009, V. Uzhinsky (hadr-prtn-V09-02-03)
|
|
Some warning were erased at FTFModel compilation.
|
|
----------------------------------------------------
|
|
3 August 2009, V. Uzhinsky (hadr-prtn-V09-02-02)
|
|
FTF model was complited by the reggeon cascade model.
|
|
-----------------------------------------------------------
|
|
17 July 2009 V. Uzhinsky (hadr-prtn-V09-02-01)
|
|
Improvement of FTF model:
|
|
A Status of nuclear nucleon involved in an interaction is introdused.
|
|
Status: 0 - spectator, 1 - involved nucleon, 2 - absorbed nucleon
|
|
(G4VSplitableHadron)
|
|
|
|
A connection between a participant nucleon and a nuclear nucleon was
|
|
introsuced in G4InteractionContent.
|
|
|
|
All of these allow to improve FTF model for pion obsorption on nuclei.
|
|
These required a lot of changes in FTF.
|
|
-------------------------------------------------
|
|
10 July 2009 V. Uzhinsky (hadr-prtn-V09-02-00)
|
|
Introduction the right tag number.
|
|
-------------------------------------------------
|
|
9 July 2009 V. Uzhinsky (hadr-prtn-V09-01-03)
|
|
Charge-exchange was implemented for pn->np in elastic and inelastic
|
|
interactions simulated by FTF. Pion absorption by a nucleon was
|
|
implemented also. tag - hadr-string-diff-V09-02-02
|
|
|
|
Bug was fixed in G4VLongitudinalStringDecay.cc at calculation of
|
|
formation/creation time, c_light was inserted. Due to this string
|
|
tension parameter was set to the usual value (1 GeV/fm) in
|
|
G4LundStringFragmentation.cc. tag - had-hadronization-V09-02-02
|
|
|
|
New field was added in G4VSplitableHadron class (G4 bool Activation)
|
|
and corresponding methods to operatite with it. It was needed for an
|
|
absorption of meson in nuclear collision generated by FTF.
|
|
tag - had-partonstring-mgt-V08-02-02
|
|
-----------------------------------------------
|
|
|
|
23 June 2008 V. Uzhinsky (hadr-prtn-V09-01-02)
|
|
G4QGSMFragmentation.cc and G4LundStringFragmentation.cc were
|
|
decoupled at calculation of formation time due to adding methods
|
|
and member in G4VLongitudinalStringDecay class for manipulation
|
|
with string tension.
|
|
|
|
Memory leak was erased in G4QGSMFragmentation.cc and
|
|
G4VLongitudinalStringDecay.cc thank to Gunter.
|
|
|
|
18 June 2008 V. Uzhinsky (hadr-prtn-V09-01-01)
|
|
Changes in G4ExcitedString class were tagged. They are needed for
|
|
operation of FTF.
|
|
|
|
13 June 2008 V. Uzhinsky (hadr-prtn-V09-01-00)
|
|
-----------------------------------------------
|
|
1. String fragmentation was revised, and parameters were tuned.
|
|
2. FTF parameters were tuned for proton-proton interaction
|
|
3. FTF parameters for pion-nucleon interactions were determined very rouhgly
|
|
4. Quiasi-elastic hadron-nucleus scattering was implemented in FTF
|
|
5. Formation time was implemented in FTF, and string tension was tuned
|
|
|

|
25 May 2007 G.Folger (hadr-prtn-V08-02-02)
|
|
-----------------------------------------------
|
|
- Seperate G4DiffractiveExcitation for FTF from QGS (see next entry by V.Uzhinsky)
|
|
- Add original G4DiffractiveExcitation to qgsm as G4QGSDiffractiveExcitation
|
|
- Move G4SingleDiffractiveExcitation from management to qgsm ( not used
|
|
elsewhere)
|
|
|
|
25 May 2007 V.Uzhinsky
|
|
-----------------------------------------------
|
|
- FTF model tuned for Pi+P interaction implemented
|
|
Moved modified G4DiffractiveExcitation from management to diffraction
|
|
|
|
24 April 2007 G.Folger (hadr-prtn-V08-02-01)
|
|
-----------------------------------------------
|
|
- Merge changes from V.Uzhinsky from ftf-dev branch back to HEAD.
|
|
- Seperate modifications done in G4VLongitudinalStringFragmentation for FTF
|
|
from original code for QGS.
|
|
- This tag includes the subdirectory tags:
|
|

|
|
-----------------------------------------------
|
|
|
|
- Add modifications of V.Uzhinsky on ftf-dev branch.
|
|
Files in diffraction, management, hadronization and qgsm are affected.

23 Nov 2005 Dennis Wright (hadr-prtn-V07-01-00)
|
|
-----------------------------------------------
|
|
|
|
- G. Folger fixed bug in hadronization/G4ExcitedStringDecay.cc
|
|
(tag had-hadronization-V07-01-00)
|
|
|
|
- D. Wright created History file for parton_string directory
|
|
|
|
31 March 2008 V. Uzhinsky (hadr-string-diff-V09-01-00)
|
|
--------------------------------------------------------
|
|
|
|
- Elastic hadron intra-nuclear nucleon scattering was inserted in
|
|
FTF model. This allows to simulate quasi-elastic and multi-particles
|
|
production together.
|
|
- Small re-orangement of FTF model was done. G4FTFCrossSection modules
|
|
were re-named into G4FTFParameters and moved to /diffraction
