Study of Twist-2 GTMDs in scalar-diquark model
Published 26 Mar 2018 in hep-ph | (1803.09406v1)
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.
