Electromagnetic Form Factors for Nucleons in Short-Range Correlations and the EMC effect

TL;DR

This paper explores how short-range correlations affect nucleon electromagnetic form factors and structure functions, suggesting that small form factor modifications do not exclude their role in explaining the EMC effect.

Contribution

It demonstrates a model linking nucleon form factor modifications to the EMC effect via short-range correlations, challenging previous claims about their significance.

Findings

Form factor modifications are comparable to structure function modifications.

Small form factor changes do not negate short-range correlations as an explanation for the EMC effect.

The model is motivated by Light-Front Holographic QCD.

Abstract

The relationship between medium modifications of nucleon electromagnetic form factors and nucleon structure functions is examined using a model motivated by Light-Front Holographic QCD (LFHQCD). These modifications are closely connected with the influence of short-ranged correlations. The size of the modifications to nucleon form factors is shown to be about the same as the modifications to the structure functions. Thus, small limits on form factors modifications do not rule out an explanation of the EMC effect motivated by the influence of short range correlations, as claimed by a recent paper.
