$B_{s}^{0} \to D_{s}^{-} a_{1}^{+}$ decay channel in the $B_{s}^{0}$ -mixing studies

Abstract

The usefulness of the $B_{s}^{0} \to D_{s}^{-} a_{1}^{+}, D_{s}^{-} \to ϕ π^{-} \to K^{+} K^{-} π^{-}, a_{1}^{+} \to ρ^{0} π^{+} \to π^{+} π^{-} π^{+}$ decay chain is investigated for the $B_{s}$ -reconstruction in the future ATLAS $B_{s}$ -mixing experiment. It is shown that this decay channel is almost as suitable for this purpose as previously studied $B_{s}^{0} \to D_{s}^{-} π^{+}$ .
