New suppressed decays of Bs mesons at CDF
arXiv:1011.3531
Abstract
The observation of new suppressed Bs decays, Bs-> J/Psi K* (892)0 and Bs->J/Psi Ks, and the measurement of their branching ratios are presented. This measurement is based on an integrated luminosity of 5.9 fb-1 of CDF data collected by a dedicated di-muon trigger. A cut based optimization is carried out for the observation of Bs -> J/Psi K*, while a neural network is used for the Bs->J/Psi Ks. In addition to the observation of the new decay modes, the ratios of branching fractions to the reference B0 decays are measured.
