Gluino-mediated electroweak penguin with flavor-violating trilinear couplings

Motoi Endo, Toru Goto, Teppei Kitahara +3

In light of a discrepancy of the direct $C P$ violation in $K \to π π$ decays, $ε^{'} / ε_{K}$ , we investigate gluino contributions to the electroweak penguin, where flavo…

Probing SUSY effects in $K_{S}^{0} \to μ^{+} μ^{-}$

Veronika Chobanova, Giancarlo D'Ambrosio, Teppei Kitahara +4

We explore supersymmetric contributions to the decay $K_{S}^{0} \to μ^{+} μ^{-}$ , in light of current experimental data. The Standard Model (SM) predicts $\mathcal{B}(K_S^0\rightarrow…

Direct $C P$ Violation in $K \to μ^{+} μ^{-}$

Giancarlo D'Ambrosio, Teppei Kitahara

A rare decay $K_{L} \to μ^{+} μ^{-}$ has been measured precisely, while a rare decay $K_{S} \to μ^{+} μ^{-}$ will be observed by an upgrade of the LHCb experiment. Although both processes ar…

Correlations of $ε_{K}^{'} / ε_{K}$ with $K \to π ν ν$ in Models of New Physics

Teppei Kitahara

Recent calculations have pointed to a 2.8 $σ$ tension between data on $ε_{K}^{'} / ε_{K}$ and the standard-model (SM) prediction. Several new physics (NP) models can explain this…

$K \to π ν ν$ in the MSSM in Light of the $ε_{K}^{'} / ε_{K}$ Anomaly

Andreas Crivellin, Giancarlo D'Ambrosio, Teppei Kitahara +1

The Standard-Model (SM) prediction for the CP-violating quantity $ε_{K}^{'} / ε_{K}$ deviates from its measured value by 2.8 $σ$ . It has been shown that this tension can be resolved…
