Double parton distributions in the nucleon from lattice QCD

Abstract We evaluate nucleon four-point functions in the framework of lattice QCD in order to extract the first Mellin moment of double parton distributions (DPDs) in the unpolarized proton. In this first study, we employ an n f = 2+1 ensemble with pseudoscalar masses of m π = 355 MeV and m K = 441...
