Insights from the Interplay of K → πνν̄ and ε K on the New Physics Flavour Structure

In certain new physics (NP) models, such as the Littlest Higgs model with T-parity, a strict correlation between the KL → π0νν̄ and K+ → π+νν̄ branching ratios has been observed, allowing essentially only for two branches of possible points, while in other NP frameworks, such as the general MSSM or warped extra dimensional models, no visible correlation… CONTINUE READING
