标题： Strong charmonium decays in a microscopic model

摘要： 尽管重夸克偶素系统的谱已成功地由某些基于QCD的势模型解释，但它们的强衰变仍是一个开放问题。 我们对矢量粲夸克偶素强衰变到开放-粲介子进行微观计算，其中$q\bar{q}$对由在夸克模型中用于描述其谱以及轻子和辐射衰变的相同夸克间相互作用产生，并且也对其强衰变宽度的不同势项可能产生的影响进行了讨论。 我们将数值结果与$^{3}P_{0}$衰变模型的预测以及现有的实验数据进行了比较，并讨论了不同势项对强宽度的可能影响。 还包含了与其他类似微观衰变模型预测的比较。 显示英文摘要

摘要： Although the spectra of heavy quarkonium systems have been successfully explained by certain QCD motivated potential models, their strong decays are still an open problem. We perform a microscopic calculation of vector charmonium strong decays into open-charm mesons where the $q\bar{q}$ pairs are created from the same interquark interactions acting in the quark model that has been used to describe its spectrum, and also its leptonic and radiative decays. We compare the numerical results with those predicted by the $^{3}P_{0}$ decay model and with the available experimental data, and discuss the possible influence on the strong widths of the different terms of the potential. A comparison with other predictions from similar microscopic decay models is also included.
