Semileptonic decays of heavy baryons are studied within the relativistic quark model based on the quasi-potential approach and quantum chromodynamics. Form factors parametrizing the matrix elements of weak transitions are calculated in the entire available kinematic interval with consistent consideration of relativistic effects. The results on the probabilities of semileptonic decays and other observable quantities are in good agreement with the available experimental data.

重子的半轻子衰变

在相对论夸克模型的基础上，基于准势方法和量子色动力学，研究了重子的半轻子衰变。在整个可用运动学间隔中，在始终考虑相对论效应的情况下，计算出参数化弱过渡矩阵元素的形状因子。半轻子衰变概率和其他可观测量的结果与现有的实验数据非常吻合。
