Proton generalized parton distributions from lattice QCD


  • Dr. Aurora SCAPELLATO

Momentum and spatial distributions of quarks and gluons are typically encoded in the so-called generalized parton distributions (GPDs). Being multi-dimensional quantities, extracting GPDs is very challenging, both experimentally and within lattice QCD. In this talk, we discuss lattice results on isovector GPDs of the proton, obtained on an ensemble of $N_f=2+1+1$ maximally twisted mass fermions, with pion mass $M_\pi=260$ MeV. Our calculations are based on the quasi-distribution formalism.
