Abstract:
Twist-three parton distribution are vital to understand the quantum nature of the hadron. The lattice simulations provide us a possibility to explore twist-three distributions more directly than the experimental measurements. I present the QCD factorization for the twist-three quasi-parton distributions gT, hL, and e, in terms of the twist-two and twist-three collinear distributions to one-loop accuracy. I demonstrate how one can extract the desired twist-three parts from the quasi-distributions by virtue of an Wandzura-Wilczek-like and Jaffe-Ji-like relations. The presentation is based on 2103.12105 and 2108.03065.
