Physics performance studies for the CBM-TRD at SIS100 energies — •Etienne Bechtel — IKF, Germany, Frankfurt

The CBM experiment will access a wide range of physics observables. The addition of the TRD is necessary for several of them, since this detector provides important electron and hadron identification capabilities. The pion suppression of the TRD, which is especially crucial in the momentum region above 1 GeV/c, will be used to look for thermal radiation from the early stages of the fireball with a sufficient signal to background ratio. This feature of the TRD is also very important for the measurement of the J/ψ,because due to it’s high mass, the J/ψ predominantly decays into dielectrons in the higher momentum region, where the TRD is primarily providing the parti- cle identification. Additionally, the dE/dx information of the four TRD layers together with the mass measurement of the TOF-detector enables the separation of light nuclei with a good resolution. This will in particular be important for the hypernuclei program of CBM.
