  We present first results on selected twist-3 quark GPDs using the
quasi-distribution method. This approach relates lattice QCD data and
light-cone distribution functions using Large Momentum Effective Theory
(LaMET). We calculate quark-antiquark correlators of boosted nucleons coupled
to non-local operators with vector and axial Dirac structure, which is
transverse to the momentum boost. We use three values of the momentum boost,
namely 0.83, 1.25, 1.67 GeV. The GPDs are defined in the symmetric (Breit)
frame, which we implement here with 4-vector momentum transfer squared of 0,
0.69 and 1.39 GeV 2 , all at zero skewness. The calculation is performed using
one ensemble of two degenerate light, a strange and a charm quark ($N_f$ = 2 +
1 + 1) of maximally twisted mass fermions with a clover term, corresponding to
a pion mass of 260 MeV.
