| 英文摘要 | Very recently, a new Omega* state was reported by the Belle Collaboration, with its mass of 2012.4 +/- 0.7(stat) +/- 0.6(syst) MeV, which locates just below the K Xi* threshold and hence hints to be a possible K Xi* hadronic molecule. Using the effective Lagrangian approach as the same as our previous works for other possible hadronic molecular states, we investigate the decay behavior of this new Omega* state within the hadronic molecular picture. The results show that the measured decay width can be reproduced well and its dominant decay channel is predicted to be the K pi Xi three-body decay. This suggests that the newly observed Omega* may be ascribed as the J(P) = 3/2(-) K Xi* hadronic molecular state and can be further checked through its K pi Xi. decay channel. |
