Abstract
We report the observation of a near-threshold enhancement in the ωJ/ψ invariant mass distribution for exclusive B→KωJ/ψ decays. The results are obtained from a 253fb-1 data sample that contains 275×106 BB̄ pairs that were collected near the Υ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. The statistical significance of the ωJ/ψ mass enhancement is estimated to be greater than 8σ.
