Comparison of EFT effects with NLO QCD and EW corrections.

Provides precise theoretical predictions for anomalous gauge interactions.

Abstract

Diboson production is of prime interest at the LHC particularly due to its sensitivity to the gauge-boson self interaction, allowing to test its Standard Model prediction with high precision and to search for possible deviations with respect to the Standard Model. We report on the results of arXiv:1804.01477, where we computed WW, WZ and ZZ production (including the leptonic decays of the vector bosons) in the effective field theory framework at NLO QCD accuracy. The impact of the higher-dimensional operators is compared to the NLO QCD and NLO EW corrections in the Standard Model. Our calculation is the first application of RECOLA2 in the effective field theory framework.
