EFT observable stability under NLO corrections through interference revival

Year: 2024

Type: article

Abstract: We illustrate the importance of interference revival when higher order corrections are included, by presenting LO and NLO differential cross-sections and K -factors for three processes that are sensitive to the dimension-6 SMEFT operator : Z -plus-two-jets ( Zjj ) production through Vector Boson Fusion (VBF), leptonic diboson WZ and Wγ . We show how lifting the interference suppression at LO, through suitable variables and cuts, is necessary to get reliable predictions at NLO. We also show bounds on obtained from these observables.
