| 英文摘要 | We report the observation of a near-threshold enhancement in the omega J/psi invariant mass distribution for exclusive B -> K omega J/psi decays. The results are obtained from a 253 fb(-1) data sample that contains 275x10(6) B(B) over bar pairs that were collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e(+)e(-) collider. The statistical significance of the omega J/psi mass enhancement is estimated to be greater than 8 sigma. |
