Sivers and Boer-Mulders GTMDs in light-front holographic quark-diquark model

We calculate the time reversal odd (T-odd) generalized transverse momentum-dependent parton distributions (GTMDs)F-1,2(o) and H(1,1)(o)and the corresponding Wigner distributions in a light-front quark-diquark model based on AdS/QCD. In the limit of zero momentum transfer, these reduce to the Sivers and Boer-Mulders TMDs, respectively. We have incorporated both scalar and axial vector diquarks in the model and obtained an overlap representation of the GTMDs using the light-front wave functions (LFWFs). Contribution from the final state interaction is incorporated at the level of one gluon exchange as a phase factor in the LFWF. We show that the final state interaction term can be factored out in this model and this part is the same for both GTMDs. We also present the Sivers and Boer-Mulders Wigner distributions in transverse momentum plane as well as in transverse impact parameter plane.
