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…
A Window onto New Invisible Particles via Semi-Visible Higgs Decays
Sally Dawson, Arnab Roy, German Valencia
Searches for new physics continue at the LHC in several forms, including new-particle searches, precision measurements of SM couplings, and searches for signals of new invisible pa…
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…
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…
Semi-visible higgs decay as a probe for new invisible particles
Sally Dawson, Arnab Roy, German Valencia
We discuss the HL-LHC sensitivity to probe new invisible particles including scalars and fermions using semi-visible Higgs decays in the $pp\to ZH, Z\to jj\, (\ell^+\ell^-), ~H\to…
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…
