A new application of the Gürsey and radicati mass formula
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.read more

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.
