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…

Monojet and direct detection constraints on real scalar dark matter: EFT and a simple UV completion

Arnab Roy, Michael A. Schmidt, German Valencia

We consider constraints that can be placed on certain invisible scalar particles through monojet studies at the LHC and compare them with those from direct detection experiments wh…

High- LHC constraints on SMEFT operators affecting rare kaon and hyperon decays

Arnab Roy, German Valencia

We consider the constraints on new physics affecting rare kaon and hyperon decay as parametrized by a low energy effective theory that can be obtained from high- observabl…

decays within the standard model and beyond

Arnab Roy, Jusak Tandean, German Valencia

Motivated by the LHCb measurement of the hyperon decay mode and prospects for improvement, we revisit the estimates for the rate and muon forward-backward asymmetr…

Constraining Asymmetric Dark Matter using Colliders and Direct Detection

Arnab Roy, Basudeb Dasgupta, Monoranjan Guchait

We reappraise the viability of asymmetric dark matter (ADM) realized as a Dirac fermion coupling dominantly to the Standard Model fermions. Treating the interactions of such a DM p…
