Description
Heavy-ion collisions at a few AGeV give insight into the intriguing hot and dense region of QCD diagram. In this region, the basic properties of hadrons, like mass or branching ratios may be modified with respect to the values in vacuum.
With rising beam energy, the production of many hadrons increases from rare to abundant. It gives a chance to obtain a multifaceted picture of created matter in extreme conditions. This pertains to (multi-)strange hadrons, strange resonances, hypernuclei, and possibly charm. The collisions are also a source of dileptons, whose measurement allows e.g. to probe the temperature of the system at the pre-freezeout stage. Also, with rising beam energy, the hadronic picture of the collision gives way to a description by quarks and gluons.
The Compressed Baryonic Matter (CBM) experiment is currently being installed at the FAIR facility. It is designed for high-precision measurements of a wide range of types of particles emitted from heavy-ion collisions. The planned reaction rate of up to 10 MHz is unprecedented. Thus, CBM is designed with radiation-hard detectors, fast electronics, and a free-streaming acquisition system. To test the performance of built components, the mCBM, an up-and-running demonstrator of CBM, is developed. The results of the in-beam tests at mCBM will be shown. They are a promising demonstration of capabilities of the future CBM setup.
