Kernel latest updates and plans Hisaya Kurashige Kobe Univ.
Event: latest updates u event-V 09 -03 -04 u Electron mass correction for ions is properly treated in G 4 Particle. Gun u u Ø Ø u G 4 Dynamic. Particle: : Add. Electron method is used Use following commands to shoot an ion /gun/particle ion /gun/ion Z A Q E event-V 09 -03 -02 u Added Get-methods to G 4 SPSEne. Distribution
Particles: latest updates 1 u particles-V 09 -03 -09 u Update mass/width based on PDG 2010 u u u Mass : t, h’, D+, Ds+, L, Xc+, Xc 0, Wc, a 0(980), f 0(1710) , K 0*(1430) Width : m, t, p+, p 0, r 0, K+, K 0, D+, D 0, Ds+, B 0, J/Y…. . particles-V 09 -03 -08, track-V 09 -03 -03 u Add new methods of G 4 Dynamic. Particle: : Get. Particle. Definition G 4 Track: : Get. Particle. Definition , which give ‘const’ pointer of G 4 Particle. Definition u u It is very dangerous to change Particle. Definition properties after initialization. Please use this method in processes. Do not use old methods of Get. Definition
Particles: latest updates 2 u track-V 09 -03 -01 u Following methods will be removed G 4 Track: : Get. Delta. Momentum() G 4 Track: : Get. Delta. Energy() u G 4 Exception(Warning) is issued if you use these methods u Use G 4 Step: : Get. Total. Energy. Deposit() to get energy deposit in the step
Particles: latest updates 3 u track-V 09 -03 -01 u u Use Physics. Vector for G 4 Track: : Get. Velocity track-V 09 -03 -04 u Fix a bug in G 4 Track: : Prepare. Velocity. Table u Get. Velocity gives wrong value around Ekin/mass ~ 100 The bug comes from mis-use of G 4 Physics. Vector Ø Physics. Vector has additional bin u G 4 Phsyics. Vector* pv = new G 4 Physics. Log. Vector(min. T, max. T, NBIN); for (G 4 int i=0; i<=NBIN; i++){ G 4 double T = pv->Energy(i); #bins is NBIN+1 not NBIN pv->Put. Value(i, func(T) ); }
Future Plan : Anti-Nuclei u Light anti-nuclei are defined as ‘shortlived’ u u anti_deuteron anti_triton anti_He 3 anti_alpha They will be moved ‘stable’ particles soon u A, Z is given by ‘positive’ number u Negative PDG code, charge, baryon number u Atomic state of anti-nuclei (i. e. anti-nuclei with positron in the orbit) is out of scope u Heavier Anti-Nuclei are not in the scope now
Future Plan : Anti-Nuclei u Processes for Anti-Nuclei Energy –Loss processes (EM statndard) are ready But u No annihilation process (hadronic process) u u An Anti-Ion will be killed after it stops (i. e. it is in Stop. And. Kill state as a result of energy loss)
