QCD factorization for twist-three axial-vector parton quasidistributions

The transverse component of the axial-vector correlation function quark fields is a natural starting object for lattice calculations twist-3 nucleon parton distribution functions. In this work we derive corresponding factorization expression in terms twist-2 and collinear distributions to one-loop accuracy. results are presented both position space, as theorem Ioffe-time distributions, momentum quasi- pseudodistributions.
