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…

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…

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…

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…

Probing Top Quark-Electron Interactions at Future Colliders

Luigi Bellafronte, Sally Dawson, Pier Paolo Giardino +1

Top quark interactions offer a window into possible new high scale physics and many models of new physics predict that the top quark interactions will deviate significantly from th…
