Projections of structure functions in a spin-one hadron

There exist new polarized structure functions in a spin-one hadron. In deep inelastic electron scattering from a spin-one hadron, there are eight structure functions F-1, F-2, g(1), g(2), b(1), b(2), b(3), and b(4). We derive projections to these eight functions from the hadron tensor W-mu nu by combinations of the hadron momentum and its polarization vectors.
