Abstract
A model for studying the leptonic weak processes of hadrons is developed on the basis of the original idea of the meson theory by Yukawa who took the strong meson as an inter mediary of /3-decay. By assuming that all strong mesons have weq.k interactions with the lepton currents, we find that the contributions from p (760) and A 1 (1070), K*, K* (890), and Kc, Kc(1240) are most prominent, leading to essentially the V-aA (a>O) type as the leptonic weak interactions of hadrons with I.JSI =0, 1. We studied the high energy neutrino reactions in this model and compared the result with experiment. Various kinds of the strong mesons lead to the diverse leptonic weak processes of hadrons; transitions .dS=O, I.JSI =1, I.JSI =2, 4S=.dQ, .dS=-.dQ'
