Description
The Compressed Baryonic Matter (CBM), currently under construction at the Facility for Anti-proton and Ion Research (FAIR) accelerator complex in Darmstadt, Germany aims to explore the QCD phase diagram at high baryon densities. Till date, no dilepton data have been collected in heavy-ion collisions at beam energies between 2A and 40A GeV. CBM aims to perform pioneering measurements of lepton pairs in nuclear collisions, employing both electron ($e^{+}e^{-}$) and muon ($\mu^{+}\mu^{-}$) channels, in the energy domain $\sqrt{s_{NN}}\sim$ 2.7 - 4.9 GeV, using unprecedented reaction rates of up to 10 MHz. The expected performance in the two channels are compared in terms of signal significances and background components. In particular the dimuon system will allow to employ charm as a probe of compressed baryonic matter via $J/\psi$ detection in p+A and A+A collisions.
