Properties of the light quarks and antiquarks in the statistical approach

TL;DR

This paper discusses the quantum statistical approach to parton distributions, focusing on the properties of light quarks and antiquarks, and highlights its consistency with recent experimental data and future challenges.

Contribution

It introduces specific properties of antiquarks derived from the statistical approach and verifies their consistency with experimental data, emphasizing future experimental tests.

Findings

Properties of antiquarks are consistent with recent data

The approach predicts specific relations between quarks and antiquarks

Future experiments will further test these properties

Abstract

In the quantum statistical parton distributions approach proposed more than one decade ago, one imposes relations between quarks and antiquarks expressions, which lead to very specific properties for the antiquarks. These properties have been verified up to now by recent data and it is a real challenge also for forthcoming experimental results, mainly in the high $x$ region.
