Neutron Parton Structure And The Light-front Spectral Function Of 3He

Light-Front Transverse Momentum Distributions for ${\cal J}$=1/2 Hadronic Systems in Valence Approximation

“…As a matter of fact, for the 3 He nucleus there exist a reliable LF spin-dependent spectral function, obtained within the Bakamjian-Thomas framework [42], suitable for embedding the wide knowledge on the nuclear interaction and the successful phenomenology developed for few-nucleon systems in a Poincaré-covariant approach (preliminary calculations of the EMC effect in 3 He were presented in Refs. [44][45][46][47] and a full calculation will be soon available [43]).…”

“…As a first test of our approach, the calculation of the EMC effect for 3 He is under way [43]. Preliminary results which consider only the contribution of the two-body bound-state channel show encouraging improvements [44][45][46][47] with respect to a convolution approach with a momentum distribution [48].…”
