A Model for Weak Interactions

概要

Three kinds of weak vector boson octet are assumed to exist. It is shown that certain modifications of the Michel theory for weak interactions, based on the new postulates for such weak boson octets, not only lead to the same results as the Cabibbo theory of the leptonic decays of hadrons, but also produce reasonable predictions for the non-leptonic decays of pseudoscalar mesons which satisfy the ΔI=1/2 rule with small violations. In particular, with specific parameter fits, the model can give G^β(β-decay)/G^μ(μ-decay)=0.980 and the same prediction as that of Cronin for K_<l4> decay. Further, for the slopes of the K→3π decays and violations of the ΔI=1/2 rule in K-meson weak decays, it gives predictions with a very good fit to experiment. In the model, we can make a reasonable description of the meson weak decays in a unified manner.
