High- $p_{T}$ 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- $p_{T}$ observabl…

$Σ^{+} \to p ℓ^{+} ℓ^{-}$ decays within the standard model and beyond

Arnab Roy, Jusak Tandean, German Valencia

Motivated by the LHCb measurement of the hyperon decay mode $Σ^{+} \to p μ^{+} μ^{-}$ 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…
