Unified framework for generalized and transverse-momentum dependent parton distributions within a 3q light-cone picture of the nucleon

We present a systematic study of generalized transverse-momentum dependent parton distributions (GTMDs). By taking speci c limits or projections, these GTMDs yield various transverse-momentum dependent and generalized parton distributions, thus providing a uni ed framework to simultaneously model different observables. We present such simultaneous modeling by considering a light-cone wave function overlap representation of the GTMDs. We construct the different quark-quark correlation functions from the 3- quark Fock components within both the light-front constituent quark model and the chiral quark-soliton model. We provide a comparison with available data and make predictions for different observables.
