Baryon decuplet mass relations in chiral perturbation theory

High Energy Physics - Phenomenology 2011-07-19 v1

Abstract

Baryon decuplet masses within an SU(3)L×SU(3)RSU(3)_L \times SU(3)_R chiral Lagrangian formalism are found to satisfy four relations at second order in flavor breaking. As a result, the one-loop corrections from Lagrangian terms up to first order in flavor breaking are observed to give finite and calculable corrections to these relations. The formal expressions for these corrections are presented, followed by numerical evaluations. We find consistency between the experimental values of breaking of the relations and the loop corrections of these relations as predicted by chiral perturbation theory.
