摘要：
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 (-> e(+) v(e)mu(-)(nu) over bar mu), WZ (-> e(-)(nu) over bar (e)mu(+)mu(-)), and ZZ (-> e(+)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 NLOEW accuracy and study the effect of the anomalous triple-gauge-boson interactions at NLO QCD. For WW and ZZ the contribution of the loop-induced gg -> W+W- and gg -> ZZ 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.
