Measurement of the branching fractions of $B_s^0 \rightarrow D_s^\mp K^\pm$, $B_s^0 \rightarrow D_s^- \pi^+$ and $B^0 \rightarrow D_s^- K^+$

The relative branching fraction of the decay $B_s^0 \rightarrow D_s^\mp K^\pm$ with respect to $B_s^0 \rightarrow D^- \pi^+$ is determined from $pp$ collision data corresponding to an integrated luminosity of 3fb$^{-1}$. From the same data, the branching fractions of $B_s^0 \rightarrow D_s^- \pi^+$...

description The relative branching fraction of the decay $B_s^0 \rightarrow D_s^\mp K^\pm$ with respect to $B_s^0 \rightarrow D^- \pi^+$ is determined from $pp$ collision data corresponding to an integrated luminosity of 3fb$^{-1}$. From the same data, the branching fractions of $B_s^0 \rightarrow D_s^- \pi^+$ and $B^0 \rightarrow D_s^- K^+$ are extracted with respect to $B^0 \rightarrow D^- \pi^+$. The obtained values for the $B_s^0 \rightarrow D_s^\mp K^\pm$ and $B^0 \rightarrow D_s^- K^+$ branching fractions are more precise than the existing world average values.
