Exploring twist-3 chiral even generalized parton distributions of light sea quarks in the proton using the light front model (2410.20737v2)

Published 28 Oct 2024 in hep-ph

Abstract: We develop a light-front model of the proton to investigate the twist-3 chiral-even generalized parton distributions (GPDs) of light sea quarks. In this model, the sea quarks are treated as spin-(\frac{1}{2}) active partons, while the remaining proton constituents are modeled as spin-1 spectators. The momentum wave function, predicted by the soft-wall AdS/QCD, is fitted to the unpolarized parton distribution functions (PDFs) from the CETQ global analysis. Using this fitted distribution, we determine the unknown model parameters. We calculate the twist-3 GPDs and analyze their dependence on the transverse momentum transfer, (\Delta_T2), and the longitudinal momentum fraction, (x). Additionally, we explore the Mellin moments and the twist-3 chiral-even PDF, (g_T(x)), within this theoretical framework.
