Di-muon measurements with the CBM experiment at FAIR

Abstract

The planned Compressed Baryonic Matter (CBM) experiment at the upcoming FAIR center at GSI, Darmstadt is aiming at the investigation of baryonic matter at high density produced in relativistic heavy-ion collisions. The research program comprises the exploration of the QCD phase diagram at high net baryon densities and moderate temperatures, the search for the de-confinement phase transition, and in-medium modifications of hadrons. The proposed key observables include the measurement of charmonia and low mass vector mesons which can be measured via their decay into the dilepton channel. In this paper, we discuss the physics motivation, detector concepts, and feasibility studies of the di-muon measurements.
