We analyze the possibility of having new physics effects in the decay rate difference, ΔΓd, of neutral Bd mesons. Three different sources of enhancement are considered, CKM unitarity violations, beyond standard model effects in the tree-level dimension six operators (dp)(p'b) with p,p'=u,c; and large enhancements of the almost unconstrained operators (db)(ττ). We find that deviations of several hundred per cent from the standard model prediction of ΔΓd are not excluded by current experimental data.
