DESCRIPTION:Speakers: ABBOTT\, Braden Keim (Department of Physics and Astr
 onomy-University of Oklahoma)\nA measurement of the relative branching fra
 ction 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 eigenst
 ate 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 Fer
 milab Tevatron Collider\, a relative branching fraction of $0.210\\pm0.032
  (\\text{stat}) \\pm 0.036 (\\text{syst})$ is found.\n\nhttp://indico.cern
