Baryons in a relativized quark model with chromodynamics

Abstract

We have studied the three-quark system in a relativized version of the quark potential model with chromodynamics. With parameters consistent with those of an analogous study of the qq\ifmmode\bar\else\textasciimacron\fi{} system, we obtain a good description of the known baryons. Our model generally supports the phenomenology of nonrelativistic calculations: it naturally explains the apparent absence of spin-orbit interactions in baryons, and leads to spectra and internal compositions for the baryons which are qualitatively similar to those of the usual nonrelativistic model.
