³He spin-dependent structure functions within the relativistic Light-Front Hamiltonian dynamics

³He spin-dependent structure functions, g³₁(x) and g³₂(x), which parametrize the hadronic tensor in polarized deep-inelastic scattering, were evaluated within the Poincar\'e covariant light-front framework. The Bakamjian-Thomas construction of the Poincar\'e generators allows us to make use of a realistic ³He wave function, obtained from refined nuclear phenomenological potentials. The same approach was already successfully applied to the ³He and ⁴He unpolarized deep-inelastic scattering. To investigate the neutron polarized structure functions, gⁿ₁ and gⁿ₂, a readily implementable procedure, aimed at extracting the neutron spin structure functions from those of ³He, is shown to hold. Moreover, the first moment of g³₁(x) was evaluated, aiming at providing a valuable check of the Bjorken sum rule. The present analysis is relevant for experiments nvolving polarized beams planned at the future facilities, like the Electron Ion Colliders.
