Measurements of the EMC effect in few-body nuclei at large x

TL;DR

This paper reports on measurements of the EMC effect in light nuclei at high x, indicating a potential dependence on local nuclear environment, and discusses future experiments to explore this further.

Contribution

It presents new experimental data on the EMC effect in light nuclei and proposes future studies to examine the influence of nuclear structure on quark distribution modifications.

Findings

Evidence suggests local nuclear environment affects the EMC effect.

Data focuses on high x region in light nuclei.

Future experiments will investigate nuclear structure influence.

Abstract

Recent data on the EMC effect from Jefferson Lab experiment E03103 suggest that the nuclear dependence of the high x quark distribution may depend on the local nuclear environment, rather than being a purely bulk effect. We briefly discuss the analysis and results of the E03103 experiment focusing on the light nuclei and high x region. In addition, we also discuss a future experiment at the upgraded 12 GeV Jefferson Lab facility which will further investigate the role of the local nuclear environment and the influence of detailed nuclear structure on the modification of quark distributions.
