  • Description: Twist-3 partonic distributions contain important information thatcharacterizes nucleon’s structure. In this work, we show our latticeexploration of the twist-3 PDFs g_T(x)gT(x),and h_L(x)hL(x).We also present our preliminary results on the twist-3 GPD\tilde{G}_2(x)G̃2(x).We use the quasi-distribution approach to connect the lattice-extractedmatrix elements, renormalized in the RI/MOM scheme, to light-conedistributions, applying the matching procedure that we developed inparallel. We also calculate the twist-2 counterparts ofg_T(x)gT(x)and h_L(x)hL(x),i.e. g_1(x)g1(x),and h_1(x)h1(x),and test the Wandzura-Wilczek approximation.
