Parton distribution of nucleon and nuclear EMC effect in a statistical model

TL;DR

This paper demonstrates that a statistical model can effectively describe the parton distribution in nucleons and the nuclear EMC effect, fitting experimental data across a broad range of momentum fractions.

Contribution

It introduces a statistical approach that captures the parton distribution and EMC effect, highlighting the significance of statistical laws in these phenomena.

Findings

Statistical model fits experimental data well across most x ranges.

Statistical laws are crucial in understanding parton distributions.

Model parameters can be tuned for accurate predictions.

Abstract

We study the parton distribution of nucleon and nuclear EMC effect in a statistical model. We find when we choose the parameters appropriately, the predictions given by pure statistical laws can fit the experimental data well in most range of $x$, this reveal statistical law play an important role in the parton distribution of nucleon.
