Combination of $\phi_s$ measurements from $B_{s}^{0}\to J/\psi\phi$ and $B_{s}^{0}\to J/\psi f_{0}(980)$
We present a combined fit to $B_{s}^{0}\to J/\psi\phi$ and $B_{s}^{0}\to J/\psi f_{0}(980)$ decays which allow us to measure the $CP$-violating phase $\phi_s$. For one of the two ambiguous solutions ($\phi_s \leftrightarrow \pi - \phi_s$) we find \begin{eqnarray} \phi_s &=& 0.03~\pm~0.16~...
