Feasibility study for the measurement of the J/Ψ particle with the sPHENIX detector

sPHENIX is a new experiment at the Relativistic Heavy Ion Collider (RHIC) in Upton, NY. The experiment was designed to study a state of nuclear matter called the Quark Gluon Plasma (QGP). We can probe the properties of the QGP by studying quarkonium production in p+p and Au+Au collisions. We have studied the feasibility of measuring J/Ψ particles decaying into electron-positron pairs with the sPHENIX detector. PYTHIA 8 was used to generate J/Ψ particle decays and the GEANT4 toolkit was used to propagate the particle through the sPHENIX detector. We determined the acceptance and reconstruction efficiency and evaluated the expected samples size in both datasets as a function of J/Ψ rapidity and transverse momentum.
