Abstract

We study analytically the branching ratio (BR) and charge parity (CP) asymmetries of the $\bar{B_{s}^{0}} \to K^{* 0} ρ^{0}$ and $K^{* 0} ω$ decay modes within QCDF approach. We find the $BR (\bar{B_{s}^{0}} \to K^{* 0} ρ^{0}) = (1.28 \pm 0.23) \times 1 0^{- 6}$ and $BR (\bar{B_{s}^{0}} \to K^{* 0} ω) = (1.12 \pm 0.58) \times 1 0^{- 6}$ . We also find the values of CP asymmetries are $𝒜_{C P}^{dir} (\bar{B_{s}^{0}} \to K^{* 0} ρ^{0}) = 0.214 \pm 0.087$ , $𝒜_{C P}^{mix} (\bar{B_{s}^{0}} \to K^{* 0} ρ^{0}) = 0.377 \pm 0.147$ , $𝒜_{C P}^{Δ Γ} (\bar{B_{s}^{0}} \to K^{* 0} ρ^{0}) = 0.901 \pm 0.051$ , $𝒜_{C P}^{dir} (\bar{B_{s}^{0}} \to K^{* 0} ω) = 0.284 \pm 0.038$ , $𝒜_{C P}^{mix} (\bar{B_{s}^{0}} \to K^{* 0} ω) = 0.835 \pm 0.024$ , and $𝒜_{C P}^{Δ Γ} (\bar{B_{s}^{0}} \to K^{* 0} ω) = - 0.471 \pm 0.063$ . The reported results are consistent with the recent theoretical predictions and can be used as a reference values in the forthcoming experiments.
