Proton generalized parton distributions from lattice QCD

Momentum and spatial distributions of quarks gluons inside hadrons are typically encoded in the so-called generalized parton (GPDs). GPDs multi-dimensional quantities that very challenging to extract, both experimentally within lattice QCD. We present first results on x-dependence isovector unpolarized, helicity transversity proton, obtained from QCD using an ensemble Nf = 2 + 1 maximally twisted mass fermions, with pion Mπ 260 MeV spacing a ' 0.093 fm. Our calculations use quasi-distribution formalism final presented MS scheme at renormalization scale GeV.
