Nuclear short-range correlations using the generalized contact formalism: new results

The generalized contact formalism (GCF) is a useful model for analyzing the properties and implications of nuclear short-range correlations (SRCs). Based on an asymptotic factorization of the wave function when two-particles are found close to each other, the GCF was used to study two-body densities and momentum distributions, electron scattering reactions, and more, resulting in a consistent and comprehensive picture regarding the effects of SRC pairs. In this talk, I will review some of the main results of the GCF, focusing on recent studies regarding neutrinoless double beta decay matrix elements, the implications of isospin symmetry and more.
