Description

Laboratories like JLAB, COMPASS and HERMES have dedicated programs focused on the investigations of Semi-inclusive DIS processes. Their results gives an opportunity to reconstruct the 3D structure of the hadron, in particular, the Transverse Momentum Distributions (TMDs). Their findings can give insights about the internal hadron dynamics as quark-gluon correlations and final-state interactions. In order to obtain the TMDs for a two-fermion bound state system, one should solve the Bethe-Salpeter equation (BSE) in the physical space. Using the Nakanishi Integral Representation and the projection onto the null plane, we obtain the functional dependence between the coupling constant and the binding energy as well as the Bethe-Salpeter Amplitudes (BSA) in ladder approximation. From the BSA we present the light-front wave functions and some preliminar calculations of the TMDs for this fermionic system.
