3He spin-dependent structure functions within the relativistic light-front Hamiltonian dynamics

He3 spin-dependent structure functions, g13(x) and g23(x), which parametrize the hadronic tensor in polarized deep-inelastic scattering, were evaluated within the Poincaré-covariant light-front framework. The Bakamjian-Thomas construction of the Poincaré generators allows us to make use of a realistic He3 wave function, obtained from refined nuclear phenomenological potentials. The same approach was already successfully applied to the He3 and He4 unpolarized deep-inelastic scattering. To investigate the neutron polarized structure functions, g1n and g2n, a readily implementable procedure aimed at extracting the neutron spin structure functions from those of He3 is shown to hold. Moreover, the first moment of g13(x) was evaluated, aiming at providing a valuable check of the Bjorken sum rule. The present analysis is relevant for experiments involving polarized beams planned at future facilities such as electron ion colliders.
