“…Experiences and R&D from CBM-STS are being used to upgrade the Baryonic Matter at the Nuclotron (BM@N)-STS under the FAIR Phase-0 framework [71,72]. BM@N-STS will comprise of 300 CBM-STS-like modules arranged as 4 tracking stations and will improve the tracking performance of the existing tracking system based on 7 planes of two-coordinate gaseous electron multiplier (GEM) detectors.…”

The Compressed Baryonic Matter (CBM) experiment is one of the major scientific pillars of the Facility for Antiproton and Ion Research (FAIR). The physics programme of CBM is centred around the exploration of the QCD phase diagram and nuclear matter equation-of-state in the region of high baryon densities. The respective rare probes will be accessed by using nucleus-nucleus collisions in the energy range √sNN = 2.9 - 4.9 GeV at peak interaction rates of up to 10 MHz and a trigger-less data acquisition scheme. This article reviews CBM physics goals with the experimental observables. The progress and current status of the comprising detector sub-systems, including their performance in FAIR Phase-0 experiments will also be presented.

“…The EOS for symmetric nuclear matter will be investigated in the near future by the upgraded BM@N experiment at the JINR-Nuclotron, where both proton flow and hyperons will be measured in Au+Au collisions at beam at energies of up to 3.8A GeV [68]. The CBM experiment at FAIR-SIS100 will study these observables for higher densities, i.e., in Au+Au collisions at beam energies up to 11A GeV [69].…”

High-energy heavy-ion collisions offer the unique possibility to study fundamental properties of nuclear matter in the laboratory, which are relevant for our understanding of the structure of compact stellar objects and the dynamics of neutron star mergers. Of particular interest are the nuclear matter equation of state (EOS), the in-medium modifications of hadrons and the degrees of freedom of matter at high densities and temperatures. Pioneering experiments exploring the EOS for symmetric matter were performed at the SIS18 accelerator of GSI, measuring, as function of beam energy, the collective flow of protons and of light fragments and subthreshold strangeness production. These data were reproduced by various microscopic transport model calculations, providing, up to date, the best constraint for the EOS of symmetric matter with an incompressibility of about 200 MeV for densities up to twice the saturation density. This article reviews the experimental results on subthreshold kaon production together with the theoretical interpretation and gives a brief outlook towards future experiments at higher densities.

“…The development and the construction of the four stations of double-sided micro-strip silicon sensors is a joint development of the BM@N and the CBM collaboration, as the same detector type is used for the CBM experiment. The upgraded BM@N experiment will be able to contribute to the search for a phase transition at large baryon chemical potentials and to the study of the high density EOS by investigating light and heavy collision systems at beam energies up to 3.8 A GeV for Au ions and up to 6 A GeV for light ions [64]. The envisaged BM@N research program includes the following observables:…”

The fundamental properties of dense nuclear matter, as it exists in the core of massive stellar objects, are still largely un-known. The investigation of the high-density equation of state (EOS), which determines mass and radii of neutron stars and the dynamics of neutron star mergers, is in the focus of astronomical observations and of laboratory experiments with heavy-ion collisions. Moreover, the microscopic degrees-of-freedom of strongly interacting matter at high baryon densities are also unknown. While Quantum-Chromo-Dynamics (QCD) calculations on the lattice find a smooth chiral crossover between hadronic matter and the quark-gluon plasma for high temperatures at zero baryon chemical potential, effective models predict a 1st order chiral transition with a critical endpoint for matter at large baryon chemical potentials. Up to date, experimental data both on the high-density EOS and on a possible phase transition in dense baryonic matter are very scarce. In order to explore this terra incognita, dedicated experimental programs are planned at future heavy-ion research centres: the CBM experiment at FAIR, and the MPD and BM@N experiments at NICA. The research programs and the layout of these experiments will be presented. The future results of these laboratory experiments will complement astronomical obser-vations concerning the EOS, and, in addition, will shed light on the microscopic degrees of freedom of QCD matter at neutron star core densities.
