相对论三夸克模型中的基态三重和二重重子

Ground-state triply and doubly heavy baryons in a relativistic three-quark model

A. P. Martynenko

摘要:

在相对论夸克模型和超球展开的框架下,计算了由三个或两个重夸克(b或c)和一个轻夸克(u,d,s)组成的基态重子的质量谱.利用三夸克哈密顿量中自旋无关和自旋相关部分的微扰理论,得到了三重和二重重子质量的预言。

英文摘要:

Mass spectra of the ground-state baryons consisting of three or two heavy (b or c) and one light (u,d,s) quarks are calculated in the framework of the relativistic quark model and the hyperspherical expansion. The predictions of masses of the triply and doubly heavy baryons are obtained by employing the perturbation theory for the spin-independent and spin-dependent parts of the three-quark Hamiltonian.
