Title
Final state interaction in two-body non-leptonic charm decay
Abstract
The final state interaction modifies the amplitudes computed within the factorization approximation to reasonably comply with the rather precise measurements on exclusive two bodies non-leptonic decay of the pseudoscalar charmed particles. In particular the large SU(3) violations shown by experiment are reproduced due to the conspiracy of the large effect of the Gell-Mann Okubo splittings on the rescattering and of the annihilation terms. Some preliminary results of the extension to final states consisting of two vector mesons will be presented.
