Simulation studies for j/psi at 12 A Gev and 30 A GeV energies Mukesh Kumar Sharma Research Scholar University of Jammu 5th CBM-India Collaboration Meeting, BHU
OUTLINE • MOTIVATION • MuCh GEOMETRY • DATA SET USED • OBSERVATION 5th CBM-India Collaboration Meeting, BHU
MOTIVATION • MuCh Detector is aimed to detect dimuon in heavy ion collision • SIS100 simulation with new geometry • Optimization of geometry • The aim is to study supression of heavy quarks resonances J/psi .The supression of these heavy quarks resonances is most promising signature of QGP 5th CBM-India Collaboration Meeting, BHU
Simulation • CbmRoot Version: Trunk version • MuCh geometry : Standard Geometry • 2 layers in 5 stations • Distance between layers ->10 cm. • Gap between absorbers ->20 cm • 3 layers at the last trigger station • Total 13 layers • Total length of MuCh = 350 cm • Signal : J/y decayed muons from Pluto • Background : minimum bias UrQMD events for Au+ Au at 12 GeV and p-Au at 30GeV for 3k events • Input : reconstructed MuCh hits Absorber thickness (cm): 20 20 20 30 35 100 5th CBM-India Collaboration Meeting, BHU
DATA SET USED • Simulation of Au-Au and p-Au at 12 GeV and 30 GeV for 3k events • Cuts used 70% hit criterion(reconstructable track) • No. of Much-hits >10 • No. of sts-Hits>4 • Event Generation Signal events->Pluto Background-> URQMD 5th CBM-India Collaboration Meeting, BHU
