$B_s^0\to D_s^{-}{a}_1^{+}(D_s^{-}\to \varphi {\pi }^{-},D_s^{-}\to K^{\ast 0}{K}^{-})$ decay channel in the ATLAS $B_s^0$-mixing studies

A. V. Bannikov, G. A. Chelkov, Z. K. Silagadze

It is shown, using a track-level simulation, that the use of the $D_s^{-}\to K^{\ast 0}{K}^{-}$ decay channel for $D_s^{-}$ reconstruction, in additioon with the previously studied $D_s^- \to…
