Abstract

Nuclear short range correlations SRCs i e the probability of finding few nucleons close to each other inside the nucleus are an integral part of the description of nuclear systems important also for neutrons star structure and for the bound nucleon structure function To study the implications of such correlations we use a new theoretical tool called the generalized contact formalism In this talk I will present the original contact formalism designed for atomic systems and our generalization to nuclear systems which allows us to derive new relations between different nuclear quantities and the probability of finding two nucleons in a close proximity inside the nucleus Among these quantities are the one body and two body momentum distributions the photo absorption cross section analyzed by Levinger using the quasi deuteron model and the Coulomb sum rule Most of these relations were verified experimentally or numerically Recently analyzing the nuclear spectral function we were also able to utilize the contact formalism to study exclusive electron scattering experimental data which is one of the main experimental tools for studying SRCs I will present direct comparison with experimental data and possible implications to the description of dense nuclear matter with nucleonic degrees of freedom
