摘要

在重夸克-反夸克介子的简化狄拉克方程框架中，更详细地研究了洛伦兹标量和质量相互作用。提出并分析了这些相互作用的微观模型。用两个自由参数再现了氙质谱;第三个参数是根据模型的现象学假设来确定的。

The Role of Scalar and Mass Interactions in a Relativistic Model of the Charmonium Spectrum

Lorentz scalar and mass interactions are studied in more detail in the framework of a reduced Dirac equation for heavy quark-antiquark mesons. A microscopic model for these interactions is proposed and analyzed. The charmonium mass spectrum is reproduced by means of two free parameters; a third parameter is fixed by means of a phenomenological hypothesis in accordance with the model.
