NCC Task Force Richard Seto NCC Task Force Meeting Nov 2, 2007 BNL
Agenda • chic update – Rich/Sky • π0 update • trigger talk - John • AOB • Next Wed (Core week) I will give an update • Would like information from pi0/chic/…. folks etc by Tues
Chic • Problem from last time • Merge • looks like • hijing bkg (single chic+hijing pp) • has 2 times more ncc hits than • pythia chic event in a pp collision • Look at raw input • hijing (zebra output) zeb2root converter • pythia – anapythia from mickey
hijing hijing 1000 pp Events min bias hijing(left) vs pythia(right) pythia 230 charged pi/event 160 charged pi/event pythia msel 1 mstp 91 1 – gausian intrinic kt parp 91 1.5 – kt value mstp 22 1 – use k factor parp 31 2.5 - kfactor
hijing hijing Interestingly if you require a chic the two are not so bad i.e.merge hijing pp with single chic (rv) = pythia with chic pythia w chic 156 charged pi/event 160 charged pi/event pythia w chic
