摘要:Generalized transverse momentum dependent parton distributions (GTMDs), as mother funtions of transverse momentum dependent parton distributions (TMDs) and generalized parton distributions (GPDs), encode the most general parton structure of hadrons. We calculate four twist-two time reversal odd GTMDs of pion in a scalar spectator model. We study the dependence of GTMDs on the longitudinal momentum fraction x carried by the active quark and the transverse momentum |k -></mml:mover>T| for different values of skewness xi defined as the longitudinal momentum transferred to the pion as well as the total momentum |Delta <mml:mo stretchy="false">-></mml:mover>T<mml:mo stretchy="false">| transferred to the pion. In addition, the quasi-TMDs and quasi-GPDs of pion have also been investigated in this paper.
