• # Abstract

We analysed the process of $B^{+}_{c} \rightarrow D^{+}_{s} \bar{K}^{0\ast}$ using QCD factorization (QCDF) and final-state interaction (FSI) effects. First, the $B^{+}_{c} \rightarrow D^{+}_{s} \bar{K}^{0\ast}$ decay is calculated using QCDF method. The value found by using theQCDF method is less than the experimental value. Then we considered FSI effect as a sizable correction wherethe intermediate state $D^{+}^{\ast}$ mesons via the exchange of $K^{0}(K^{0}^{\ast}$) are produced. To consider the amplitudes ofthis intermediate state, the QCDF approach was used. The experimental branching ratio of $B^{+}_{c} \rightarrow D^{+}_{s} \bar{K}^{0\ast}$ decayis less than $0.4 \times 10^{-6}$ and our results are $(0.21 \pm 0.04) \times 10^{7}$ and $(0.37 \pm 0.05) \times 10^{6}$ from QCDF and FSI,respectively.
