Abstract |
We study the D0 ->rho 0 phi, omega phi decays which proceed in a direct mode via internal emission with equal rates. Yet, the experimental branching ratio for the rho 0 phi mode is twice as big as that for the omega phi mode. We find a natural explanation based on the extra indirect mechanism where K*+K*- is produced via external emission and that channel undergoes final state interaction with other vector-vector channels to lead to the rho 0 phi, omega phi final states, with transition amplitudes dominated by the a0(1710) resonance, recently discovered, and f0(1710) respectively. The large coupling of the a0(1710) to the rho 0 phi channel is mostly responsible for this large ratio of the production rates. |
