Description

A measurement of the relative branching fraction of $B^0_s\to J/\psi f_0(980)$, $f_0(980)\to\pi^+\pi^-$ to $B^0_s\to J/\psi \phi$, $\phi\to K^+K^-$ is presented. The decay mode $B^0_s\to J/\psi f_0(980)$ is an interesting mode since it is a CP eigenstate and allows the measurement of the CP-violating phase $\phi_s$. Using approximately 8 fb$^{-1}$ of data recorded with the D0 detector at the Fermilab Tevatron Collider, a relative branching fraction of $0.210\pm0.032 (\text{stat}) \pm 0.036 (\text{syst})$ is found.
