Abstract

W+WW^+ W^- 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 W+WW^+ W^- 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 WW- boson rapidity and transverse momentum as well as WWWW invariant mass are presented. The γγ\gamma \gamma components only constitute about 1-2 \% of the inclusive W+WW^+ W^- cross section but increases up to about 10 \% at large W±W^{\pm} transverse momenta, and are even comparable to the dominant qqˉq \bar q component at large MWWM_{WW}, i.e. are much larger than the ggW+Wg g \to W^+ W^- one.
