Models for TMDs and numerical methods

We present a systematic study of the transverse-momentum- dependent parton distributions (TMDs) in the framework of quark models. In particular, we review the general formalism for modeling the quark TMDs using the representation in terms of overlap of nucleon light-cone wave functions. Such a formalism can be applied to a large class of quark models. We will discuss the building blocks of these different models, and we will use as explicit example for the calculation of the TMDs a light-cone constituent quark model. Within this model, we also propose a phenomenological study of different observables, trying to learn how model parameters related to particular assumptions on the nucleon structure can be tuned to describe available experimental data.
