Chiral-odd generalized parton distributions of spin-1/2 baryons

TL;DR

This paper explores the detailed internal structure of spin-1/2 baryons using chiral-odd generalized parton distributions, calculated within a diquark spectator model focusing on transverse momentum transfer.

Contribution

It introduces a calculation of four chiral-odd GPDs for baryons using a light-front diquark model at zero skewness, highlighting flavor-dependent differences.

Findings

Predictions for nucleons and hyperons show flavor-dependent GPD differences.

The model provides a tomographical view of baryon structure.

Results emphasize the role of tensor currents in baryon tomography.

Abstract

We present the tomographical structure of baryons by studying the nonforward matrix elements of lightlike correlation functions of the tensor current. At the leading twist, with the tensor current, four chiral-odd distributions are in count. We calculate these distributions in a diquark spectator model with light-front formalism by considering purely transverse momentum transfer, i.e., zero skewness. Predictions for the nucleons and light hyperons are studied, emphasizing the difference arising from their different quark flavors.
