Test for universality of short-range correlations in pion-induced Drell-Yan Process

TL;DR

This paper examines whether short-range correlations in nuclei are universal by analyzing pion-induced Drell-Yan processes and proposing a universal modification function to test this hypothesis.

Contribution

It introduces a universal modification function for nuclear effects in pion-induced Drell-Yan processes, enabling tests of SRC universality across different nuclei.

Findings

Proposed a universal modification function for nuclear effects.

Presented ratios of differential cross sections for various nuclei.

Enhanced understanding of nuclear structure and strong interactions.

Abstract

We investigate nuclear modification and the universality of short-range correlation (SRC) in pion-induced Drell-Yan process. Employing nuclear parton distribution functions (nPDFs) and pion PDFs, the ratio of differential cross sections of different nuclei relative to the free nucleon is presented. A kind of universal modification function was proposed which would provide nontrivial tests of SRC universality on the platform of pion-induced Drell-Yan. This work improves our understanding of nuclear structure and strong interactions.
