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

Abstract

We report the results of a search for $B^{-} \to \jpsi Λ\pbar$ based on a data set of 78 fb${}^{-1}$ data collected at the ${\rm Y}(4S)$ 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 ${\cal B}(B^{-} \to \jpsi Λ\pbar) < 4.1 \times 10^{-5}$ at 90% confidence level.
