Moments of axial-vector GPD from lattice QCD: quark helicity, orbital angular momentum, and spin-orbit correlation
Abstract In this work, we present a lattice QCD calculation of the Mellin moments of the twist-2 axial-vector generalized parton distribution (GPD), H ~ x ξ t $$ \overset{\sim }{H}\left(x,\xi, t\right) $$ , at zero skewness, ξ, with multiple values of the momentum transfer, t. Our analysis employs t...
