量子力学偶极求和规则和ψ(3770)的电偶极跃迁

Dipole Sum Rules in Quantum Mechanics and Electric Dipole Transitions of ψ(3770)

本文对量子力学偶极求和规则进行了一些普遍的讨论。利用这些求和规则估算了φ(3770)的电偶极跃迁宽度的上限和下限。结果表明,Mark Ⅲ组给出的实验值明显偏大。

Dipole sum rules in quantum mechanics are generally discussed. The upper and the lower bounds on the electric dipole transition widths of ψ(3770) are estimated. It evidently indicates that the experimental values obtained by Mark Ⅲ collaboration are much larger than the theoretical expectations.
