Precision Empirical Mass Formulae for Baryon Octet and Decuplet
Abstract
Description
Empirical mass formulae for the baryon octet and decuplet are presented. These formulae are functions of one integer variable and charge state of the baryons. With an exception of Lambda(1116), the formulae generate masses within 0.1% of the observed masses. The formulae also generate the same electromagnetic mass splittings predicted by SU(6)model. Spin 1/2 octet resonances and its relation to the octet mass formula is described.
