EFT matching from analyticity and unitarity
Stefano De Angelis, Gauthier Durieux
We present a new on-shell method for the matching of ultraviolet models featuring massive states onto their massless effective field theory. We employ a dispersion relation in the…

LHC EFT WG Note: Basis for Anomalous Quartic Gauge Couplings
Gauthier Durieux, Grant N. Remmen, Nicholas L. Rodd +5
In this note, we give a definitive basis for the dimension-eight operators leading to quartic -- but no cubic -- interactions among electroweak gauge bosons. These are often called…

Triboson production in the SMEFT
Eugenia Celada, Gauthier Durieux, Ken Mimasu +1
We study the production of three electroweak gauge bosons at the LHC, in the effective field theory of the standard model, at dimension six and next-to-leading order in QCD. We pre…
