We report the observation of a near-threshold enhancement in the omegaJ/psi invariant mass distribution for exclusive B-->KomegaJ/psi decays. The results are obtained from a 253 fb(-1) data sample that contains 275 x 10(6) BB 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 omegaJ/psi mass enhancement is estimated to be greater than 8sigma.
我们报告了在排他性B→KωJ/ψ衰变的ωJ/ψ不变质量分布中观察到的近阈值增强。结果来自一个253 fb⁻¹的数据样本，该样本包含在KEKB非对称能量e⁺e⁻对撞机上，使用Belle探测器在Upsilon(4S)共振附近收集的275×10⁶个BB对。ωJ/ψ质量增强的统计显著性估计大于8σ。
