In this paper, decay constants, lepton and photon decay widths for radially and orbitally excited conventional, as well as hybrid, charmonium mesons are calculated. The Schrödinger equation with non-relativistic potential model is used to obtain the spectrum and the radial wave function at the origin for the S and the P states conventional, as well as hybrid, charmonium mesons. The calculated spectrum agree with experimental findings within a 0.43-GeV standard deviation. The leptonic decay widths agree with other theoretical results, but are lower than the experimental measurements. The two-photon decay widths for 1 S 0 and 3 P 2 states are in agreement with the experimental findings, but that for the 3 P 0 states is not.

常规和混合 Charmonium 介子的衰减特性

在这篇论文中，计算了径向和轨道激发的常规以及混合的珲介子的衰变常数、轻子和光子衰变宽度。具有非相对论势模型的薛定谔方程用于获得 S 和 P 状态常规以及混合的卡莫尼姆介子的光谱和原点处的径向波函数。计算出的光谱在 0.43-GeV 标准偏差内与实验结果一致。轻子衰变宽度与其他理论结果一致，但低于实验测量值。1 S 0 和3 P 2 态的双光子衰减宽度与实验结果一致，但3 P 0 态的双光子衰变宽度与实验结果不一致。
