Towards an improved description of SiDIS by a polarized 3He target
The possibility of improving the description of the semi-inclusive deep
inelastic electron scattering off polarized 3He, that provides information on
the neutron single spin asymmetries, is illustrated. In particular, the
analysis at finite momentum transfers in a Poincare' covariant framework is
outlined and a generalized eikonal approach to include final state interaction
is presented.Comment: 4 pages, 2 figures, presented at The 22nd European Conference on Few

Neutron Transverse-Momentum Distributions and Polarized 3He within Light-Front Hamiltonian Dynamics
The possibility to extract the quark transverse-momentum distributions in the
neutron from semi-inclusive deep inelastic electron scattering off polarized
3He is illustrated through an impulse approximation analysis in the Bjorken
limit. The generalization of the analysis at finite momentum transfers in a
Poincare' covariant framework is outlined. The definition of the light-front
spin-dependent spectral function of a J=1/2 system allows us to show that
within the light-front dynamics only three of the six leading twist T-even
transverse-momentum distributions are independent.Comment: 4 pages, 2 figures, Presented at the 20th International IUPAP
