A novel equation of state for nuclear and hadronic matter with induced surface tension

Short range particle repulsion is proven to be rather important property of the hadronic and nuclear matter equation of state. A novel approach is presented, based on the virial expansion for a multicomponent system with hard core repulsion. A contribution of surface tension induced by particle interaction is a principally new element of that approach. Applications of this equation of state to the description of hadronic multiplicities measured in A+A collisions, the nuclear matter phase diagram and to modelling neutron star interiors are discussed.
