# Ab initio short-range-correlation scaling factors from light to medium-mass nuclei

## TL;DR

This paper uses ab initio nuclear theory to calculate short-range correlation scaling factors across light to medium-mass nuclei, linking high-energy scattering data with low-energy nuclear structure predictions.

## Contribution

It introduces a method to predict SRC scaling factors from effective field theory, connecting high-energy scattering phenomena with ab initio nuclear calculations.

## Key findings

- SRC scaling factors can be predicted from low-energy nuclear theory.
- EMC effect and SRC factors have minimal isovector corrections.
- Calculations extend to medium-mass nuclei.

## Abstract

High-energy scattering processes, such as deep inelastic scattering (DIS) and quasielastic (QE) scattering provide a wealth of information about the structure of atomic nuclei. The remarkable discovery of the empirical linear relationship between the slope of the European Muon Collaboration (EMC) effect in DIS and the short-range-correlation (SRC) scaling factors $a_2$ in QE kinematics is naturally explained in terms of scale separation in effective field theory. This explanation has powerful consequences, allowing us to calculate and predict SRC scaling factors from ab initio low-energy nuclear theory. We present ab initio calculations of SRC scaling factors for a nucleus $A$ relative to the deuteron $a_2(A/d)$ and relative to $^3\rm He$ $a_2(A/^3\rm He)$ in light and medium-mass nuclei. Our framework further predicts that the EMC effect and SRC scaling factors have minimal or negligible isovector corrections.
