Observation of B+ ∧ ∧K+

The observation of the hyperonic B+ → λλ̄K+ decay was presented. It was found that the rate of a charmless B decay was comparable to that of other charmless three-body baryonic modes. It was also found that the invariant mass of the λλ̄ system had a prominent near-threshold peak. The observed results show that the measurement achieved has the first observation of a meson decay to a hyperon pair.
