Hi all,
I have produced quite amount of fast simulation data with before updated verion of mar14, so with first version of mar14 since yesterday evening.
I see taht not only neutral list has been fixed but also few things have been updated by Klaus for Mdt(MUO) PID and EMC PID part since yesteday afternoon.
Since when exactly Mdt and EMC PID has been fixed? First version or updated version.
Best wishes,
Donghee

Hi,
there is another issue which I'd like to mention: At the moment, the default behaviour of DPM Gen is to hand particles like pi0, K_S, Lambda, etc, over to Geant without decaying them. Therefore these events are not suitable for the fast simulation studies where no transport software is used.
Aida is currently working to implement a possibility to control this by parameters. Therefore you either have to patch DPMGen in your own pandaroot (pgenerators/DpmEvtGen/init.f, lines 140ff)
136 C-----------------------------------------------------------------
137 C IF IT IS NEEDED TO POINT OUT THE OTHER STABLE
138 C PARTICLES, PUT CORRESPONDING ISTAB = 1
139 C-----------------------------------------------------------------
140 IDSTAB(17)=1 ! \Lambda
141 IDSTAB(18)=1 ! Anti_Lambda
142 IDSTAB(19)=1 ! K^0_s
143 IDSTAB(23)=1 ! \pi^0
144 C IDSTAB(33)=1 ! \rho_0
145 ccc aida
146 c IDSTAB(31)=1 ! eta
147 c IDSTAB(35)=1 ! omega
148 c IDSTAB(95)=1 !eta'
by setting the IDSTAB parameters to 0 and recompiling, or you wait for the official update from Aida.
Best,
Klaus
