“…Dynamical nuclear effects in inclusive deep inelastic electron scattering (DIS) 3 He(e, e ′ )X (DIS) were evaluated [6] with a realistic 3 He spin-dependent spectral function, P τ σ,σ′ (p, E, S He ), with p the initial nucleon momentum in the laboratory frame and E the missing energy [7].

“…In such a framework, SSAs for 3 He involve convolutions of P τ σ,σ ′ (p, E, S He ), with TMDs and ffs. Ingredients of the calculations were: i) a realistic P τ σ,σ ′ (p, E, S He ) for 3 He, obtained using the AV18 interaction; ii) parametrizations of data for TMDs and ff, whenever available; iii) models for the unknown TMDs and ff. It was found that, in the Bjorken limit, the extraction procedure through the formula successful in DIS works nicely for the Sivers and Collins SSAs [9].…”

“…The LF spectral function will be very useful also for other studies (e.g., for nuclear generalized parton distributions (GPDs), where final states have to be properly boosted, studied so far only within a non-relativistic spectral function [17; 18]). The LF nuclear spectral function, P τ σ ′ σ (κ, ǫ S , S He ), is defined in terms of LF overlaps [19] between the ground state of a polarized 3 He and the cartesian product of an interacting state of two nucleons with energy ǫ S and a plane wave for the third nucleon. Within a reliable approximation [19] it can be given in terms of the unitary Melosh Rotations, D …”

The analysis of semi-inclusive deep inelastic electron scattering off polarized 3 He at finite momentum transfers, aimed at the extraction of the quark transverse-momentum distributions in the neutron, requires the use of a distorted spin-dependent spectral function for 3 He, which takes care of the final state interaction effects. This quantity is introduced in the non-relativistic case, and its generalization in a Poincaré covariant framework, in plane wave impulse approximation for the moment being, is outlined. Studying the light-front spin-dependent spectral function for a J=1/2 system, such as the nucleon, it is found that, within the light-front dynamics with a fixed number of constituents and in the valence approximation, only three of the six leading twist T-even transverse-momentum distributions are independent.
