Weak (quasi-)PDFs from the lattice

Future colliders will be able to probe the electroweak substructure of particles. An accurate description of this substructure may necessitate electroweak PDFs, similarly to QCD. We investigate therefore the Higgs and W/Z PDFs in a reduced Standard Model setup using lattice methods, determining the quasi-PDFs, and, to lowest order, the resulting PDFs. While uncertainties remain, the results show interesting structures in line with expectations from gauge invariance.
