粲偶素态间辐射衰变的分析

Analysis of the radiative decays among the charmonium states

Zhi-Gang Wang

摘要:

本文用重夸克有效理论研究了粲偶素态间的辐射衰变,并预言了一个特殊多重态与另一个多重态的辐射衰变宽度之比。这些预测结果可以与实验数据进行比较,并对$X$,$Y$,$Z$类粲介子的识别提出了新的约束条件。

英文摘要:

In this article, we study the radiative decays among the charmonium states with the heavy quark effective theory, and make predictions for the ratios among the radiative decay widths of an special multiplet to another multiplet. The predictions can be confronted with the experimental data in the future and put additional constraints in identifying the $X$, $Y$, $Z$ charmonium-like mesons.
