Chiral-odd generalized parton distributions for proton in a light-front quark-diquark model

TL;DR

This paper investigates chiral-odd generalized parton distributions (GPDs) for protons using a light-front quark-diquark model derived from AdS/QCD, providing numerical results in various spaces and skewness conditions.

Contribution

It introduces a novel calculation of chiral-odd GPDs in a light-front quark-diquark model based on AdS/QCD, including comprehensive numerical analysis.

Findings

GPDs are expressed as overlaps of light-front wave functions.

Numerical results are provided for momentum and transverse position spaces.

GPDs are evaluated for both zero and nonzero skewness in different spatial representations.

Abstract

We present a study of the chiral-odd generalized parton distributions for $u$ and $d$ quarks in a proton using the light front wave functions of the scalar quark-diquark model for nucleon constructed from the soft-wall AdS/QCD correspondence. We obtain the GPDs in terms of overlaps of the LFWFs. Numerical results for chiral-odd GPDs in momentum as well as transverse position spaces considering both zero and nonzero skewness($\zeta$) are presented. For nonzero skewness, the GPDs are also evaluated in longitudinal position space.
