Connecting scaling with short-range correlations

Abstract

We reexamine several issues related to the physics of scaling in electron scattering from nuclei.A basic model is presented in which an assumed form for the momentum distribution having both long-and short-range contributions is incorporated in the single-particle Green function. From this one can obtain saturation of nuclear matter for an NN interaction with medium-range attraction and short-range repulsion, and can obtain the density-density polarization propagator and hence the electromagnetic response and scaling function. For the latter, the shape of the scaling function and how it approaches scaling as a function of momentum transfer are both explored.

Multinucleon excitations in neutrino-nucleus scattering: connecting different microscopic models for the correlations

“…The way of connecting the scaling with short-range correlation has been discussed in Ref. [59]. In the present article, which is somewhat of pedagogical nature, we establish the explicit connection between the dressed nucleon moving in a mean field and the bare correlated nucleon, for which the coupling to the external probe is known.…”
