利用Belle实验积累的数据，通过初态辐射过程研究矢量粲偶素和类粲偶素通过辐射跃迁产生电荷共轭宇称为正的粲偶素和类粲偶素，寻找X(3872)、XYZ（3940）、X(3915)、Y(4140)、X(4350)等。这些测量可能建立矢量粲偶素或类粲偶素与这些粒子之间的联系，从而为理解它们的内在结构和产生与衰变性质，以及深入理解量子色动力学理论提供实验数据，促进理论的完善和发展。同时我们利用Belle积累的Upsilon(1S)和Upsilon(2S)数据研究其强子衰变，结合BESIII上的粲偶素衰变研究，探讨对"rho pi"疑难的深入理解。在研究的前期，我们用Belle的数据进行分析，积累分析经验，以保证2016年运行后，Belle II数据一旦采集，马上可以进行相关研究。

With the data samples collected with the Belle experiment, we study the charmonium and charmoniumlike states, bottomonium and bottomoniumlike states with initial state radiation, and the transitions between the heavy quarkonia. We will search for the possible radiative transitions between the vector charmonium and charmoniumlike states and the charged conjudate parity even XYZ states such as X(3872), XYZ(3940), X(3915), Y(4140), X(4350) and so on. These information will possibly connect the exotic states with different quantum numbers, and will be helpful for understanding of their intrinsic properties, and shed light on a better understanding of the quantum chromodynamics. At the earlier stage of the study, we will use the Belle data first to gain experience on how to select events, how to reduce the background and so on, and will use these experience as soon as the Belle II data are available in 2016.
