Abstract

Stability of strange quark matter is investigated within a chiral model which implements the scale anomaly of QCD. As far as quark confinement is mimicked by a large value of the u-quark mass, the model behaves in the chirallimit as a MIT bag model: it yields a stable system composed of quarks surrounded by the vacuum. As soon as finite current quark masses are taken into account, stability is however lost, (C) 2001 Elsevier Science B.V. All rights reserved.
