摘要：

We consider the long distance contributions to inclusive penguin processes through processes like b --> sV and b --> dV where V are S-3(1)(CE) states psi(i) in the former case and include rho, omega for the latter case. We carefully examine vector dominance for <(c)over bar c> states, and conclude that there is a large suppression of psi similar to gamma transition when psi is at q(2) = 0. The long distance effects can be at most 7% in the amplitude for b --> s gamma. The long distance contribution to b --> dy is also found to be small.
