Correlation effects on the weak response of nuclear matter

TL;DR

This paper investigates how correlation effects influence the weak response of symmetric nuclear matter across different momentum transfers, using a correlated basis function approach with realistic nucleon-nucleon interactions.

Contribution

It introduces a unified dynamical model that accounts for both short- and long-range correlations in nuclear response calculations.

Findings

Identifies dominant interaction effects in specific kinematical regions

Uses correlated basis functions with realistic nucleon-nucleon forces

Provides insights into the nuclear response at various momentum transfers

Abstract

The consistent description of the nuclear response at low and high momentum transfer requires a unified dynamical model, suitable to account for both short- and long-range correlation effects. We report the results of a study of the charged current weak response of symmetric nuclear matter, carried out using an effective interaction obtained from a realistic model of the nucleon-nucleon force within the formalism of correlated basis functions. Our approach allows for a clear identification of the kinematical regions in which different interaction effects dominate.
