论文摘要
我们解决了不同内核中重型伪尺度的瞬时伯特 - 钙板方程，其中使用线性标量电势以及Feynman Gauge，Landau Gauge，colomb Gauge，coulomb仪表和时间组分量量表的一个Gluon Exchange Vector势能获得内核。我们获得了重型伪镜的质谱，并比较了不同内核之间的结果，发现使用相同的参数，我们获得了时间成分库仑（Coulomb）的最小质量分裂，这是Feynman和Coulomb Gauges中相似的最大质量分裂，在Landau量表中分裂。
We solved the instantaneous Bethe-Salpeter equation for heavy pseudoscalars in different kernels, where the kernels are obtained using linear scalar potential plus one gluon exchange vector potentials in Feynman gauge, Landau gauge, Coulomb gauge and time-component Coulomb gauge. We obtained the mass spectra of heavy pseudoscalars, and compared the results between different kernels, found that using the same parameters we obtain the smallest mass splitting in time-component Coulomb gauge, the similar largest mass splitting in Feynman and Coulomb gauges, middle size splitting in Landau gauge.
