Revisiting the $\Gamma (K\to e\nu )/\Gamma (K\to \mu \nu )$ ratio in supersymmetric unified models

R. M. Fonseca, J. C. Romao, A. M. Teixeira

It has been pointed out that supersymmetric extensions of the Standard Model can induce significant changes to the theoretical prediction of the ratio $Γ(K\rightarrow eν)/Γ(K\right…
