TLDR
In this article, the average energy of SU(6) multiplet is described using a hypercentral potential containing a linear and a hyper-Coulomb term, which is the same as in this paper.
Abstract
We study the spin- and flavour-dependent SU(6) violations in the baryon spectrum by means of a Gursey-Radicati mass formula. The average energy of each SU(6) multiplet is described using the SU(6)-invariant interaction given by a hypercentral potential containing a linear and a hyper-Coulomb term. We show that the nonstrange- and strange-baryon masses are, in general, fairly well reproduced and moreover that the Gursey-Radicati formula holds in a satisfactory way also for the excited states up to 2 GeV.

Baryons in a relativized quark model with chromodynamics

TL;DR: The three quark system is studied in a relativized version of the quark potential model with chromodynamics and the spectrum of baryons is described with parameters consistent with those of an analogous study of meson spectroscopy.

Hadron Masses in a Gauge Theory

TL;DR: In this paper, the authors explore the implications for hadron spectroscopy of the "standard" gauge model of weak, electromagnetic, and strong interactions, and use the asymptotic freedom of the model to argue that for the calculation of hadron masses, the short-range quark-quark interaction may be Coulomblike.

P Wave Baryons in the Quark Model

TL;DR: In this article, the spectrum and mixing angles of negative-parity baryons in a quark-model framework inspired by quantum chromodynamics were discussed, and good agreement with experiment in the $S = 0$ and $S=\ensuremath{-}1$ sectors were obtained.
