NLO EW and QCD dimension-6 SMEFT results for Higgs and gauge boson decays in POPxf format
Luigi Bellafronte, Sally Dawson, Clara Del Pio +2
We present next-to-leading-order (NLO) QCD and electroweak (EW) results using the dimension-6 SMEFT for all 2- and 4- body Higgs decays, for and decays along with the corre…
Parametrisation and dictionary for CP violating Higgs boson interactions
Daniele Barducci, Matthew Forslund, Marta Fuentes Zamoro +3
Searches for charge-parity (CP) violating interactions of the Standard Model (SM) Higgs boson are a key priority of the LHC physics program. Experimental results from ATLAS and CMS…
Higgs Decays at NLO in the SMEFT
Luigi Bellafronte, Sally Dawson, Clara Del Pio +2
The calculation of precise predictions for Higgs decays is a necessary ingredient for determining Higgs properties at the LHC and future colliders. We compute all two- and three-bo…
Complete NLO SMEFT Electroweak Corrections to Higgs Decays
Luigi Bellafronte, Sally Dawson, Clara Del Pio +2
Precise predictions for Higgs decays are a crucial ingredient of the search for beyond the Standard Model (BSM) physics and the Standard Model Effective Field Theory (SMEFT) is a v…
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…
