Description

In this talk we will have a brief look at the two decay modes $B_s^0\to J/\psi \varphi$ and $B_s^0\to \psi (2S)\varphi$ and the measurement of the corresponding ratio. To guarantee identical topologies between the two decays we have chosen to only look at the $\psi (2S)\to {\mu }^{+}{\mu }^{-}$ and $J/\psi \to {\mu }^{+}{\mu }^{-}$ modes. A quick look at the peaking backgrounds $B_s^0\to J/\psi f_0(980)$ and $B_s^0\to \psi (2S)f_0(980)$ is also given attention.
