He had predicted the existence of and 2 mesons, and formulated the selection rule " " S " } } for semi-leptonic decays of strange particles.

Also, it allowed the study of the leptonic decay of ? + and ? " particles, and confirmed the validity of the ?Q / ?S = + 1 rule.

Several results for neutral kaons were obtained and published in the early 1970s, including the observation of the rare decay of the neutral kaon to a muon pair, the time-dependence of the asymmetry for semi-leptonic decays, and a more precise measurement of the neutral kaon mass difference.
