摘要:

本工作使用非相对论夸克势(NRQP)模型计算了粲偶素(cc)的质谱、辐射衰变和强衰变。通过数值求解径向薛定谔方程得到波函数,进一步用于计算cc态的辐射衰变宽度;采用3P0模型结合简谐(SHO)波函数计算强衰变宽度,通过拟合数值波函数得到不同cc态的SHO参数η值。我们将结果与实验数据及其他理论预测结果对比,为粲偶素态X(3940)、X(3872)、X(3862)、X(4350)分别指定了可能的量子数:ηc(3S)、χ1(2P)、χ0(2P)和χ2(3P)。

英文摘要:

In this work, we have calculated the mass spectrum, radiative decays, and strong decays of charmonium (cc) by using the non-relativistic quark potential(NRQP) model. The wave functions are calculated by solving the radial Schrodinger equation numerically, which are further used to compute the radiative decay widths of (cc) states. The 3P0 model is used to calculate the strong decay widths by using the simple harmonic (SHO) wave functions. The SHO parameter \b{eta} values for different cc states are calculated by fitting it to the numerical wave functions. We also compare our results with experimental data and other theoretically predicted results. We assign to the charmonium states X(3940), X(3872), X(3862), X(4350) likely quantum numbers of ηc(3S), \c{hi}1(2P), \c{hi}0(2P) and \c{hi}2(3P) states.
