Abstract

Strongly interacting matter at extremely high net-baryon density has drawn a renewed interest, and high-energy heavy ion collision experiments are being performed worldwide to study such a matter. The high net-baryon densities produced in energetic heavy ion collisions are similar to those in the core of a neutron star, although the temperature is high. The equation of state and other properties of such a medium sheds light on the nature of the medium including the formation of a deconfined state of quarks and gluons called quark–gluon plasma (QGP). One such upcoming dedicated high-density experiment at FAIR-Germany called compressed baryonic matter (CBM) will be discussed in detail.
