Query: Neutron Parton Structure And The Light-Front Spectral Function Of 3He   Semi-inclusive deep inelastic electron scattering off polarized 3He is
studied in a non-relativistic framework, using a distorted spin-dependent
spectral function for 3He to take care of the final state interaction between
the observed pion and the remnant. A simple procedure is shown to be valuable
for the extraction of Sivers and Collins asymmetries for the neutron fromthe
corresponding asymmetries for 3He. To extend this study in a relativistic
framework, a novel approach for a Poincar\'e covariant description of nuclear
dynamics is presented, based on the light-front Hamiltonian dynamics. The key
quantity is the light-front spectral function, where both normalization and
momentum sum rule can be satisfied at the same time. Preliminary results are
discussed for an initial analysis of the role of relativity in the EMC effect
in 3He, and the generalization of the procedure for the extraction of neutron
asymmetries within the light-front dynamics is outlined.
