Description
The Compressed Baryonic Matter (CBM) experiment at FAIR is designed to explore
the QCD phase diagram in the region of high baryon densities and moderate
temperatures. The key CBM observables include particles containing hidden charm –
J/y and Y’, open charm – D0, D+ , D* and Lc, low-mass vector mesons decaying into
leptons and multi-strange hyperons. Particularly demanding is the measurement of
open charm particles with very low multiplicities, which is based on the real time
selection of displaced vertices with an accuracy of about 50 μm. In the talk we
discuss the problems of the detection of heavy-quark particles in fixed target
experiments with relativistic heavy ion collisions.
