Abstract

In this work, we study the generalized transverse momentum dependent distribution (GTMD) E21E_{21} for proton using light-front quark-diquark model. We construct the expression of E21E_{21} GTMD using the overlap equation in light-front wave functions obtained from the GTMD correlator with Dirac matrix structure Γ=1\Gamma=1, in both situations of scalar and vector diquark. The 33-dimensional plots of GTMD E21E_{21} have been analyzed with respect to its variables by taking two variables at a time while holding others constant.
