The Compressed Baryonic Matter (CBM) experiment at the future FAIR facility at Darmstadt will measure dileptons emitted from the hot and dense phase in heavy-ion collisions. Very fast event reconstruction is extremely important for CBM because of the huge amount of data which has to be handled. In this contribution the parallel event reconstruction(More)
Results on the energy dependence of charged pion and kaon production in central Pb+Pb collisions at 40, 80 and 158 A·GeV are presented and compared with data at lower and higher energies. The mean pion multiplicity increases approximately linearly with s 1/4 with a change of slope around 40 A·GeV. The change from pion suppression with respect to p+p(More)
The CBM muon detection system is designed to measure muon pairs from the decay of vector mesons (ρ, ω, φ, J/ψ) produced in heavy-ion collisions. At FAIR energies the muon momenta can be rather low, therefore, we developed a muon detection concept which a variable definition of absorber thickness according to the muon momentum was been developed. The(More)
In November 2010 the CBM-RICH group together with other CBM groups took part in a test beamtime at CERN PS target area T10. We report on first results from the analysis of the obtained data. Our goal for this beamtime was to further study the Cherenkov photon detection with Hamamatsu H8500 Mul-tianode PMTs using a proximity focusing test setup. This test(More)
The CBM muon detection system (MuCh) was optimized for nucleus-nucleus collisions at SIS300 beam energies (see [1]). We have investigated the possibility to simplify the setup for measurements of J/ψ mesons in proton-nucleus collisions at SIS100 beam energies. Therefore, the performance of the muon detection system has been studied as function of the number(More)

In this contribution we present new developments and results for the LIT track reconstruction package for CBM in the CbmRoot framework. The reconstruction package is organized to be flexible with respect to feasibility studies of different physics channels and to optimization of the detector geometries. The tracking software has been redesigned to make it(More)
The RICH detector in CBM shall provide electron identification together with the TRD detectors for the measurement of low-mass vector mesons and charmonium in the di-electron decay channel. Both observables are considered key probes for the study of compressed baryonic matter in heavy ion collisions. A RICH design based on first general considerations has(More)
