协变Faddeev方程的重子性质

Baryon properties from the covariant Faddeev equation

Helios Sanchis-Alepuz, Reinhard Alkofer, Richard Williams

摘要:

本文计算了Delta和Omega重子的质量和电磁性质,以及它们随当前夸克质量的演化。因此,采用了广义的Bethe-Salpeter方法,将相互作用截断为修饰的单胶子交换。通过研究两种形式的缀饰胶子交换,探讨了模型依赖性。

英文摘要:

A calculation of the masses and electromagnetic properties of the Delta and Omega baryon together with their evolution with the current quark mass is presented. Hereby a generalized Bethe-Salpeter approach with the interaction truncated to a dressed one-gluon exchange is employed. The model dependence is explored by investigating two forms for the dressed gluon exchange.
