| 英文摘要 | pi(+)pi(-) transitions of heavy quarkonia, especially the Upsilon(3S) -> Upsilon(1S)pi(+)pi(-) decay process axe studied. An effective Lagrangian is employed and the S wave pi pi final state interaction (FSI) is included in the framework of the Chiral Unitary Theory (ChUT). It is found that when an additional intermediate state with J(P) = 1(+) and I = 1 is introduced, the experimental data can be well-explained, and a consistent description of bottomonium pi(+)pi(-) transitions can be obtained. As a consequence, the mass and the width of the intermediate state are predicted. From the quark content analysis, this state should be a bbqq state. |
