Structure of Nuclear Matter at Short Distances

Abstract

In the past decades, considerable advances have been made both in experimentally studying and in theoretically describing properties of cold nuclear matter at short nucleon-nucleon distances. In the present study, it is shown that, in addition to the commonly known method of studying the structure of nuclei at short distances in processes of deep-inelastic lepton scattering, processes of particle production in nucleus-nucleus reactions beyond the kinematics of nucleon-nucleon collisions are an important complementary source of information. Some predictions concerning the behavior of special features that are peculiar to such processes and which one can extract from experimental data obtained for collisions of gold nuclei at an energy of 2.4 GeV in the HADES experiment at the GSI (Gemeinschaft für Schwerionenforschung) research center (Darmstadt, Germany) are presented.
