To Study the tracking efficiency performance of J/ψ and ψ' using CBM much setup

Abstract

Relativistic heavy ion collision makes it possible to study the fundamental con- stituents of the matter. High-resolution detectors are required to detect the rare probes like the decay of J/ψ into dimuon. One such a kind is CBM detector which will be working at moderate temperature and high baryonic density of QCD phase diagram. As the detector is in a developing stage, we are trying to design the detec- tor through simulation. In first part of the work we compared the transport engine GEANT3 and GEANT4 through point density at 12 AGeV minimum bias Au-Au collision. In second part we are trying to find the effciency of CBM MuCh detector using the rare decay channel of dimuon through J/ψ. We tried finding the efficiency of J/ψ in pT regime through the division of reconstructed by generated counts of dimuon. The simulation is done at 25 AGeV for 105 Au-Au central collision.
