$W^+ W^-$ pair production in proton-proton collisions: small missing terms
Abstract
production is one of the golden channels for testing the Standard Model as well for searches beyond the Standard Model. We discuss many new subleading processes for inclusive production of pairs generally not included in the litterature so far. We focus mainly on photon-photon induced processes. We include elastic-elastic, elastic-inelastic, inelastic-elastic and inelastic-inelastic contributions. We also calculate the contributions with resolved photons including the partonic substructure of the virtual photon. Predictions for the total cross section and differential distributions in - boson rapidity and transverse momentum as well as invariant mass are presented. The components only constitute about 1-2 \% of the inclusive cross section but increases up to about 10 \% at large transverse momenta, and are even comparable to the dominant component at large , i.e. are much larger than the one.
