Abstract: (Springer)
Diboson production at the LHC is a process of great importance both in the context of tests of the SM and for direct searches for new physics. In this paper we present a phenomenological study of WW\mathrm {W}\mathrm {W}  ( e+νeμνˉμ\rightarrow \mathrm {e^+}\nu _{\mathrm {e}}\mathrm {\mu ^-}\bar{\nu }_{\mu } ), WZ\mathrm {W}\mathrm {Z}  ( eνeμ+μ\rightarrow \mathrm {e^-}\overline{\nu }_{\mathrm{e}} \mu ^+ \mu ^- ), and ZZ\mathrm {Z}\mathrm {Z}  ( e+eμ+μ\rightarrow \mathrm {e^+}\mathrm {e^-}\mu ^+ \mu ^- ) production considering event selections of interest for the anomalous triple-gauge-boson-coupling searches at the LHC: we provide theoretical predictions within the Standard Model at NLO QCD and NLO EW accuracy and study the effect of the anomalous triple-gauge-boson interactions at NLO QCD. For WW\mathrm {W}\mathrm {W} and ZZ\mathrm {Z}\mathrm {Z} the contribution of the loop-induced ggW+W\mathrm {g}\mathrm {g}\rightarrow \mathrm {W}^+\mathrm {W}^- and ggZZ\mathrm {g}\mathrm {g}\rightarrow \mathrm {Z}\mathrm {Z} processes is included. Anomalous triple-gauge-boson interactions are parametrized in the EFT framework. This paper is the first application of Recola2 in the EFT context.
