Search for B^- --> J/psi Lambda p-bar decay

Abstract

We report the results of a search for B^{-} \to \jpsi \Lambda \pbar based on a data set of 78 fb$^{-1}$ data collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric $e^+ e^-$ collider. No substantial signal is found, and we set the branching fraction upper limit {\cal B}(B^{-} \to \jpsi \Lambda \pbar) < 4.1 \times 10^{-5} at 90% confidence level.Comment: 8 pages, 2 figures, submitted to Phys.
