Query: Simultaneous muon and reference hadron measurements in the Compressed
  Baryonic Matter experiment at FAIR   The mission of the Compressed Baryonic Matter (CBM) experiment at the future
Facility for Antiproton and Ion Research (FAIR) in Darmstadt is to explore the
QCD phase diagram at high net baryon densities likely to exist in the core of
neutron stars. The CBM detector system is designed to perform
multi-differential measurements of hadrons and leptons in central gold-gold
collisions at beam energies between 2 and 11 A GeV with unprecedented precision
and statistics. In order to reduce the systematic errors of the lepton
measurements, which generally suffer from a large combinatorial background,
both electrons and muons will be measured with the same acceptance. Up to now,
no di-muon measurements have been performed in heavy-ion collisions at beam
energies below 158A GeV. The main device for electron identification, a Ring
Imaging Cherenkov (RICH) detector, can be replaced by a setup comprising hadron
absorbers and tracking detectors for muon measurements. In order to obtain a
complete picture of the reaction, it is important to measure simultaneously
leptons and hadrons. This requirement is fulfilled for the RICH, which has a
low material budget, and only little affects the trajectories of hadrons on
their way to the Time-of-Flight (TOF) detector. In contrast, the simultaneous
measurement of muons and hadrons within the same experimental acceptance poses
a substantial challenge. This article reviews the simulated performance of the
CBM experiment for muon identification, together with the possibility of
simultaneous hadron measurements.
