Lopes, J L

The Chew static model of meson theory predicts transition probabilities for the capture of mu mesons by nuclei about twenty times smaller than the experimental data. This seems to indicate that the interaction of muons with nucleons is probably not the result of a direct coupling of these particles with the pion field. The data are consistent with a Fermi direct coupling of muons with nucleons. The quality of the couplings is discussed. The triangle of interactions among nucleons, muons, and electrons can be extended to encompass a presumable coupling of leptons with pairs of hyperons with the same strangeness quantum number. This implies a beta decay of hyperons with rate of the same order of magnitude as that of the neutron. The mu decay of K mesons through closed loops is discussed. lt requires the assumption of a further coupling of muons and of electrons with pairs of baryons with different strangeness. The absence of the beta decay of K mesons can be accoumted for. One obtains, however, a beta decay rate for the DELTA /sub o/ which is about 3% of the observed decay rate, for a Fermi scalar coupling. The possible interactions are discussed. (auth)
