Electromagnetic Form Factors for Nucleons in Short-Range Correlations and the EMC effect (2404.15442v2)
Published 23 Apr 2024 in nucl-th and hep-ph
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 paper.
