As is well known, protons and neutrons consist of up-quarks, down-quarks and gluons to hold the quarks together. In fact, other kinds of quarks are present, too. The precise way that the momentum of a high-energy proton is carried by the quarks and gluons cannot be directly calculated and must be inferred from measurements. Some of the most useful measurements are done at hadron colliders like the LHC at CERN and the Tevatron at Fermilab, using W and Z bosons as “probes.” I will explain the importance of some of these measurements and highlight the most interesting ones recent and describe how they can help improve our models of the proton.
