The Matter Density Distribution for Mesons and Baryons

TL;DR

This paper investigates the internal matter density distribution of mesons and baryons using gauge-invariant methods, revealing that hadron deformation results from relativistic quark motion.

Contribution

It introduces a gauge-invariant approach to evaluate matter density distributions in hadrons, comparing quenched and unquenched theories.

Findings

Matter density distributions are successfully computed for mesons and baryons.

Hadron deformation is linked to relativistic quark motion.

Comparison with charge density suggests deformation arises from relativistic effects.

Abstract

The matter density distribution inside a hadron is evaluated using gauge-invariant correlation functions within the quenched and the unquenched theory. Comparison with the charge density distribution suggests that hadron deformation is a consequence of the relativistic motion of the quarks.
