摘要
用瞬时近似下的Ｂｅｔｈｅ－Ｓａｌｐｅｔｅｒ（Ｂ－Ｓ）方程，讨论了０－重介子束缚态．运用重味质量展开方法求解方程，计算了一级近似下Ｄ±，Ｄ０，Ｂ±，Ｂ０介子的质量，与实验数据和其它求解方法的计算结果作了比较．
heavy meson bound states are discussed by using the Bethe-Salpeter (B-S)equation at the instantaneous approximation. In terms of the heavy flavor mass expansion method, the masses for mesons D0, D±, B0, B± are calculated at first order approximation. Comparisons of our results with experimental data and with some theoretical calculations from other method are given.
