Quark and Gluon GPD Global Analysis with DVCS and DVMP at NLO

Speaker

Fatma Aslan (JLab)

Description

We use the GUMP (Generalized Parton Distributions (GPDs) through Universal Moment Parametrization) framework, based on the conformal moments of GPDs, to perform a unified global analysis incorporating Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP) data. By performing simultaneous fits across these processes and incorporating Next-to-Leading Order (NLO) corrections, we are able to constrain the valence quark, sea quark and gluon GPDs.
