Contribution of hadronic intermediate states in non-leptonic weak decays of K, Charm and B mesons

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We demonstrate that contributions of hadronic intermediate states can give a possible solution to puzzles in non-leptonic weak decays of K and charm mesons, in particular, exotic four-quark mesons play an essential role in charm meson decays and also in the small violation of the so-called |ΔI|=1/2 rule in K→ππ decays. A brief comment on B-meson decays is also provided.
