Two-particle nonleptonic decays of D and F mesons, and structure of weak interactions
Voloshin M.B. , Zakharov V.I. , Okun' L.B.
We consider nonleptonie decays of the hypercharged (charmed) D and F mesons. Relations are obtained between the amplitudes of different decays, which follow from unitary symmetry and from the assumption that the Hamiltonian of the weak interactions takes the form of the product of a current by a current. We consider the consequences of the T-, £/-, and F-spin selection rules.
