Impact of NLO EW and QCD corrections to dimension-6 SMEFT coefficients constraints in Higgs decays
Luigi Bellafronte, Ana Rosario Cueto Gómez, Sally Dawson +4
This paper presents the impact of the inclusion of next-to-leading-order (NLO) QCD and electroweak (EW) corrections for dimension-6 Standard Model Effective Field Theory (SMEFT) pr…

Field Redefinitions Can Be Nonlocal
Timothy Cohen, Matthew Forslund, Andreas Helset
We revisit the lore establishing the allowed space of field redefinitions and show that there are essentially no restrictions. Our conclusions hold to all orders in perturbation th…

NLO SMEFT Electroweak Corrections to Higgs Decays to 4 Leptons in the Narrow Width Approximation
Sally Dawson, Matthew Forslund, Pier Paolo Giardino
Some of the most precise measurements of Higgs boson couplings are from the Higgs decays to 4 leptons, where deviations from the Standard Model predictions can be quantified in the…
