Description
Summary:To study the high-density nuclear equation-of-state in collisions between gold nuclei at Nuclotron beam energies (2–4.5 A GeV), the existing BM@N experiment at JINR in Dubna has to be substantially upgraded. The measurement of high-multiplicity events at interaction rates up to 5 MHz requires the installation of four large-aperture tracking stations equipped with double-sided micro-strip silicon sensors, which have been developed for the CBM experiment at FAIR. It has been demonstrated by simulations that the hybrid tracking system comprising four of such silicon stations (STS) situated in-front of seven GEM tracking detectors will be able to identify charged particles including hyperons emitted in Au + Au collisions with good efficiency and high signal-to-background ratio. The results of the simulations and the status of the STS detector development are presented.
