Study of Twist-2 GTMDs in scalar-diquark model

Abstract

We investigate the Generalized Transverse Momentum-dependent Distributions (GTMDs) describing the parton structure of proton using the light-front scalar-diquark model. In particular, we study the Wigner distributions for unpolarized quark in unpolarized, longitudinally-polarized and transversely-polarized proton. We also investigate the twist-2 GTMDs for unpolarized quark $(\Gamma ={\gamma }^{+})$ in scalar-diquark model.
