Deformed solutions of the MIT quark bag model

Abstract

The authors have solved the quark confinement boundary-value problem of the MIT bag model numerically for axially deformed bag shapes. As first results they present a Nilsson-type level diagram for quarks confined in a deformed cavity. Minimising the baryon energy with respect to the shape parameters, they also calculate the masses of baryonic states. Here the results show very clearly that excited baryon resonances are intrinsically deformed.
