二体和三体通量管模型的相对论修正

Relativistic corrections for two- and three-body flux tube model

F. Buisseret, C. Semay

摘要:

本文将相对论通量管模型推广到任意两体或三体系统。在微扰下计算了磁通管对总哈密顿量的自旋无关和自旋相关贡献。特别是,我们表明,自旋相关的部分表现出普遍的自旋轨道形式:它不依赖于约束粒子的性质。我们提出的一般方程,被定义为轻粒子,因此可以适用于常见的以及奇异的强子,如混合介子和胶球。

英文摘要:

We generalize the relativistic flux tube model for arbitrary two- or three-body systems. The spin-independent and spin-dependent contributions of the flux tube to the total Hamiltonian are computed in perturbation. In particular, we show that the spin-dependent part exhibits a universal spin-orbit form: It does not depend on the nature of the confined particles. The general equations we present, being well-defined for light particles, can thus be applied to usual as well as exotic hadrons such as hybrid mesons and glueballs.
