Quark Helicity and Transversity Distributions

TL;DR

This paper investigates the fundamental differences between quark helicity and transversity distributions inside nucleons, aiming to clarify their origins and discrepancies through theoretical analysis.

Contribution

It provides a detailed analysis of the underlying reasons for the differences between quark helicity and transversity distributions, which are less understood in nucleon structure.

Findings

Identifies key factors causing the discrepancy between helicity and transversity distributions

Clarifies the theoretical origin of differences in quark distributions

Enhances understanding of nucleon spin structure

Abstract

The quark transversity distribution inside nucleon is less understood than the quark unpolarized and helicity distributions inside nucleon. In particular, it is important to know clearly why the quark helicity and transversity distributions are different. We investigate the origin of their discrepancy.
