Scientific paper

A realistic study of the SiDIS process 3He(e,e'\pi)X in the Bjorken limit is briefly reviewed, showing that the nuclear effects, present in the extraction of the neutron information, are largely under theoretical control, within an Impulse-Approximation approach. In view of the forthcoming experimental data, we shortly present a novel Poincare' covariant description of the nuclear target, implementing a Light-Front analysis at finite Q^2, within the Bakamijan-Thomas construction of the Poincare' generators. Furthermore, as a by-product of the introduction of a Light-Front spin-dependent spectral function for a J=1/2 system, we straightforwardly extend our analysis to the quark-quark correlator, obtaining three new exact relations between the six leading-twist Transverse-Momentum Dependent distributions.
