Abstract:

Weak decay processes of kaons and charmed pseudo-scalar mesons are analysed by using urbaryon diagrams assuming current-current interaction. The relation between the diagrams and the possible selection rule (Δn_t = 0 rule) are discussed and sum rules for charmed meson decays are given. Crucial test for our approach is also presented.
