Contribution of hadronic intermediate states in nonleptonic weak decays of K, charm and B mesons

摘要

We demonstrate that contributions of hadronic intermediate states are important in nonleptonic weak decays of K and charm mesons. Among various hadrons, exotic mesons can play an essential role in charm meson decays and also in the small violation of the so-called (Delta)I = 1/2 rule in K (yields) (pi)(pi) decays. The same technique is applied to B meson decays. (author).
