Abstract

Twist-3 partonic distributions contain important information that characterizes nucleon's structure. In this work, we show our lattice exploration of the twist-3 PDFs gT(x)g_T(x), and hL(x)h_L(x). We also present our preliminary results on the twist-3 GPD G~2(x)\tilde{G}_2(x). We use the quasi-distribution approach to connect the lattice-extracted matrix elements, renormalized in the RI/MOM scheme, to light-cone distributions, applying the matching procedure that we developed in parallel. We also calculate the twist-2 counterparts of gT(x)g_T(x) and hL(x)h_L(x), i.e. g1(x)g_1(x), and h1(x)h_1(x), and test the Wandzura-Wilczek approximation.
