PREDICTION OF RE EPSILON FROM K13 DECAYS IN AN EXTENDED CABIBBO MODEL

With the help of an extended Cabibbo model for the weak hadronic vector current which includes the 10 and -10 representations to account for possible ΔS=-ΔQ transitions, a prediction is made for the quantity (1-|x|2)/|1-x|2 where x=A(K0→πüe--v)/A(-K0→πüe--v) using the experimental branching ratio Γ(K-→ π0e--v/Γ(KL0→πüe--v). From the known charge asymmetry in the decay of the long lived kaon one then obtains Re e{open}. © 1969 Springer-Verlag.
