NLO QCD and EW corrections to triple-W production with leptonic decays in proton-proton collisions
Multiboson production processes are paramount to investigate the triple and quartic gauge couplings arising in the SM and provide a direct window to the process of electroweak symmetry breaking. A precise theoretical prediction is necessary to confront theory with data and search for physics beyond the SM. I will present a NLO EW and QCD calculation of WWW production with leptonic decays in proton–proton collisions. Beside the full off-shell calculation, I will present results in the triple-pole approximation, expanding transition amplitudes around the three W resonances.
