Search for the Rare Decay $$B_s^0 \to \mu^+\mu^-$$ at D0
- Rice Univ., Houston, TX (United States)
Results of the search for the rare decay B0 s → μ+μ- using data collected by the D0 detector at the Fermilab Tevatron collider are presented. This analysis covers the full Run II data set, corresponding to approximately 10.4 fb-1 of integrated luminosity in p¯p collisions at a center of mass energy of 1.96 TeV. The analysis used new variables and a multivariate technique to improve the background reduction. After seeing fewer events than expected from background, a new Tevatron best observed limit was set on the branching fraction of the decay at B(B0 s→ μ+μ-) < 15 x 10-9 (12 x 10-9) at the 95% (90%) C.L.
