Smearing effects ofρ-meson width onDPVdecays

Abstract
We study the effects of mass averaging over the width of the ρ meson on branching ratios of DPV decays. This smearing effect ensures lowering of these ratios in the required direction by about 25%. We calculate the smeared branchings for the Cabibbo-enhanced, -suppressed, and -doubly-suppressed DDsPρ decays in the presence of final-state interactions.
