 o Role of condensates?
 o Role of meson cloud?
 o Origin of mass?
 o Nature of confinement?

Challenges

Theory Simulation of a heavy-ion collision at SIS18 energies.
 o non-perturbative Laboratory for many questions related to the QCD EOS.
 o sign problem (lQCD)

Experiment
 o finite size and lifetime
 o rare diagnostic probes

FAIR Phase-0
The exploration of the QCD phase diagram has started

Successful run in March 2019 for
Ag-Ag collisions at = 2.6 GeV.
 q 15 Billion Events in 30 days

 q RICH detector has been equipped
 with new photo camera using the
 CBM MAPMT and jointly developed
 read-out electronics.

 q Photon camera boosted the lepton
 pair detection capability by a factor
 ten.

 q First time dilepton pairs beyond 1
 GeV invariant mass

 q Data can be used to study detector
 response in all details and to
 introduce it to the CBM performance
 studies

FAIR Phase-0
CBM time-of-flight (RPC) enables STAR FXT program

36 CBM RPC modules have been
installed at the end-cap of the STAR
detector.
 q Extends the Beam Energy Scan down
 in energy by run STAR in fix-target
 mode.
 q BESII running from Dec. 2019 – 20th
 of Mar. 2020 (corona break, restart
 planned for June).
 q Fixed target program completed,
 about 100 M events for each energy
 (7.7 GeV, 6.2 GeV, 5.2 GeV, 4.5 GeV,
 3.9 GeV, 3.5 GeV).
 q System time resolution better than 85
 ps, PID capability demonstrated.
 q Perfect test bed to study the detector
 performance

 o [200ns] correlations of subsystems in the
 common, synchronized data stream.
