Description
The plan for future Electron-Ion collider (EIC) aims to open the regime of experimental detection of distribution functions (DFs) consisting of a new range of polarization states of parton and its parent nucleon. This demands the theoretical advancement of parton distributions at all levels of twist. By detangling the quark-quark generalized parton correlation functions (GPCFs) at various limits, we have obtained the higher twist (twist-3 and/or twist-4) parton distribution functions (PDFs), generalized parton distributions (GPDs), transverse momentum-dependent parton distributions (TMDs) and generalized transverse-momentum dependent parton distributions (GTMDs) in the light-front quark-diquark model. These DFs have been expressed in the overlap form as well as the explicit form of the light-front wave functions (LFWFs) while considering both scalar and vector diquark possibilities. The model-dependent and independent relations of these distributions have also been explored extensively.
