Projections of structure functions in a spin-one hadron

Abstract

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 ${W}^{\ensuremath{\mu}\ensuremath{\nu}}$ by combinations of the hadron momentum and its polarization vectors.
