Description
Nucleon Mellin moments of parton distribution functions and generalized parton distributions are computed up to the fourth order in lattice QCD. The computation is performed using one ensemble of twisted mass fermions at the physical pion mass point. We employ boosted frames to access the higher-order Mellin moments of generalized parton distributions. We also extract the generalized formfactors up to fourth order. These results establish benchmarks for future lattice studies and expand the understanding of the partonic structure of the proton.
