Ribon (hadr-prtn-stable-V10-02-06/hadr-prtn-V10-02-03) 21 G4FTFParameter : set SetExcitationEnergyPerWoundedNucleon to 40 MeV. 22 23 -------------------------------------------------- 24 01 December 2016, A. Ribon (hadr-prtn-stable-V10-02-05/hadr-prtn-V10-02-02) 25 G4FTFParameter : changed SetExcitationEnergyPerWoundedNucleon 26 from 100 MeV (as in G4 10.1) to 80 MeV (it was 40 MeV in G4 10.2). 27 28 -------------------------------------------------- 29 09 November 2016, A. Ribon (hadr-prtn-stable-V10-02-04/hadr-prtn-V10-02-01) 30 G4ExcitedStringDecay : increased the number of max attempts to 31 fragment strings from 10 to 100. 32 33 -------------------------------------------------- 34 12 October 2016, A. Ribon (hadr-prtn-stable-V10-02-03/hadr-prtn-V10-02-00) 35 G4VPartonStringModel : instead of having the string creation loop 36 (with max 20 attempts) and the string fragmentation loop (with max 37 100 attempts) separated, there is now one single loop for string 38 creation and fragmentation, with max 1000 attempts, and in the case 39 of failure a just-warning exception is thrown. 40 41 -------------------------------------------------- 42 11 October 2016, A. Ribon (hadr-prtn-stable-V10-02-02) 43 G4FTFModel : brought back completely, as in G4 10.1, the treatment 44 of the residual nucleus excitation energy (there were a few places 45 which were forgotten in the tag cms_hadr-string-diff-V10-01-17). 46 47 -------------------------------------------------- 48 11 October 2016, A. Ribon (hadr-prtn-stable-V10-02-01) 49 First clean-up and identation of the code. 50 No changes of the random number sequence. 51 52 -------------------------------------------------- 53 06 October 2016, A. Ribon (hadr-prtn-stable-V10-02-00) 54 Created first (internal) tag of the stable parton_string branch. 55 This corresponds to parton_string as in G4 10.2.p02 , with the special 56 (internal) tag cms_hadr-string-diff-V10-01-17 on top of diffraction, 57 in order to bring the residual nucleus excitation energy as it was in 58 G4 10.1 . 59 The aim of this stable parton_string branch is to produce hadronic 60 showers, with either FTF or QGS string models, very similar to those 61 in G4 10.1, which are reasonably good for the LHC experiments. 62 63 ================================================== 64 65 -------------------------------------------------- 66 26 March 2014, G.Folger (hadr-prtn-V10-00-02) 67 convert to const G4Particledefinition* 68 69 -------------------------------------------------- 70 25 February 2014, A.
