S. M. Gerasyuta, E. E. Matskevich

摘要:

在相对论夸克模型下计算了负宇称$(70,1^-)$底非奇异重子的质量。在色散关系的框架下,导出了$(70,1^-)$底重子多重态的相对论性三夸克方程。利用基于提取振幅前导奇点的方法,得到了这些方程的近似解。预测了21个重子的质量。

英文摘要:

The masses of negative parity $(70,1^-)$ bottom nonstrange baryons are calculated in the relativistic quark model. The relativistic three-quark equations of the $(70,1^-)$ bottom baryon multiplet are derived in the framework of the dispersion relation technique. The approximate solutions of these equations using the method based on the extraction of leading singularities of the amplitude are obtained. The masses of 21 baryons are predicted.
