Investigation of the General Transverse Momentum Distribution Function in Light-front Wave Function Method

In anlogous to hadron, electron has similar structure because of dressing. So we can define the Transverse Momentum Distribution functions (TMD), the General Parton Distribution functions (GPD) and General Transverse Momentum Distribution functions (GTMD) of electron which come from the Wigner distribution function. The GTMD contain the information of momentum and position of parton in one particle, and the GPD or TMD can be calculated by integration of transverse momentum or setting the transverse transfer momentum which equal to zero. We introduce the light-front wave function of electron to calculate the GTMD of dressed electron, and then get the TMD and GPD. Our results are verified by comparing to calculations in literature and the contribution of GPD of P-wave and S-wave. And we show that the distribution functions at different transverse momentum transfer, transverse momentum of parton and the fraction of longitudinal momentum.
