Description
Compressed Baryonic Matter (CBM) is a fixed-target experiment that is part of the Facility for Antiproton and Ion Research (FAIR) that currently is under construction. Its primary objective is to investigate the phase diagram of strongly interacting matter (QCD) under conditions of high net-baryon density and moderate temperature. This will be achieved by studying heavy-ion and hadron collisions in the energy range sNN=2.9−4.9 GeV.
CBM employs advanced, fast, radiation-tolerant detector systems and an advanced data acquisition approach. With the ability to operate at interaction rates of up to 10 MHz, it performs real-time space-time event reconstruction and selection. This enables the study of rare phenomena, including multi-strange hadrons, their antiparticles, multi-strange hypernuclei, and dileptons, many of which remain underexplored.
This talk will highlight CBM’s scientific objectives, such as probing the equation of the state of compressed nuclear matter, searching for potential phase transitions between the hadronic and partonic phases, and exploring the restoration of chiral symmetry. The presentation will delve into CBM’s physics capabilities in areas like (multi-)strange particle production, dilepton spectroscopy, collective flow, and femtoscopy. Additionally, the current progress in CBM's construction will be discussed, featuring performance studies of its components in FAIR Phase-0 experiments and results from the mCBM test setup using SIS18 beams.
