Due to its non abelian nature, the Standard Model gauge group allows the presence, among others, of a charged Triple Gauge Coupling (cTGC) γ∗/ZW+W− between a neutral and two charged electroweak gauge bosons. Such coupling can receive Beyond the Standard Model (BSM) contributions, leaving open the possibility of anomalous cTGC not yet constrained by electroweak precision measurements. We focus on W+W− production, which can be probed both at hadron and lepton colliders, presenting a feasibility study for searches for BSM contributions in cTGC both at present and future colliders.

Abstract
Due to its non abelian nature, the Standard Model gauge group allows the presence, among others, of a charged Triple Gauge Coupling (cTGC) γ∗/ZW+W− between a neutral and two charged electroweak gauge bosons. Such coupling can receive Beyond the Standard Model (BSM) contributions, leaving open the possibility of anomalous cTGC not yet constrained by electroweak precision measurements. We focus on W+W− production, which can be probed both at hadron and lepton colliders, presenting a feasibility study for searches for BSM contributions in cTGC both at present and future colliders.File in questo prodotto:
