| contents | In light of the recent data for $\bar{B}_{(s)}\to D^{(*)}_{(s)}P$ and $\bar{B}_{(s)}\to D_{(s)}V$ decays, we perform a model-independent phenomenological analysis in the presence of quasi-elastic rescattering. With the Wilson coefficients including contributions beyond the standard model, lifetimes of $B$ meson as well as the $B^0_d-\bar{B}^0_d$ mixing are investigated for clarifying correlations among the observables. We show that parameter regions for quasi-elastic rescattering, the size of color-suppressed tree amplitudes and new physics are constrained due to the lifetime data. As a consequence, it is revealed that this scenario can be testable by the future LHCb measurement of width difference in $B^0_d-\bar{B}^0_d$ mixing and semi-leptonic CP asymmetry. |
