Properties of the X(3872) at Belle
Abstract
We report recent results on the properties of the X(3872) produced via the B+ --> K+ X(3872) decay process. We observe X -->pi+pi-pi0 J/psi decays where the 3pi invariant masses cluster near the upper kinematic boundary suggesting that they originate from sub-threshold decays to virtual omega(782) mesons. This is consistent with expectations for a DD*-bar bound state interpretation for the X(3872). In addition, we constrain the possible charmonium-state assignments for this particles. Results are obtained from a 253/fb data sample that contains 274 million BB-barr pairs that was collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider.
