摘要

介绍了用于研究单体和n体相互作用系统的Dirac方程的一般局部约简方法。在单体情况下，我们表明，这种约简允许狄拉克方程的近似解，使波函数的上下分量相关联。对两体情况进行了更详细的研究。我们证明了该方法可以防止引入虚假的非物理状态。这种简化也适用于另一个相对论方程。最后，利用该方法建立了具体的模型，对Charmonium谱进行了研究。

A Local Reduction of the Dirac Equation Applied to the Study of Quark Interactions

A general procedure of local reduction for the Dirac equation is introduced to study one- and n-body interacting systems. In the one-body case we show that the reduction allows for an approximate solution of the Dirac equation, correlating the upper and the lower components of the wave function. The two-body case is studied in more detail. We show that the method prevents from introducing spurious, unphysical states. The reduction is also applied to another relativistic equation. Finally, the method is used to construct a specific model in order to study the Charmonium spectrum.
