The first type is the weak kaon decay [special characters omitted] The interest here is this decay's sensitivity to the loop-level and hence quantum structure of the standard model. Both short-distance and long-distance effects are considered, as well as possible contributions from horizontal gauge bosons. The second decay type studied is electromagnetic η decays into neutral pions, specifically [special characters omitted] and [special characters omitted] The main interest here is possible signals for electromagnetic charge-conjugation violation. The modelling method used is vector meson dominance. The third type studied is electromagnetic η decays into charged pions, specifically [special characters omitted] and [special characters omitted] The interest here is chiral perturbation theories that incorporate vector mesons.enAvailable to the World Wide WebMesonsKaonPionsThesis
