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…

Scalar dark matter explanation of the excess in the Belle II $B^{+} \to K^{+} +$ invisible measurement

Xiao-Gang He, Xiao-Dong Ma, Michael A. Schmidt +2

Recently Belle II reported the first measurement of $B^{+} \to K^{+} + invisible (inv)$ , which is $2.7 σ$ above the standard model (SM) prediction. If confirmed, this calls for new p…
