Abstract
An alternative to introducing and subsequently renormalizing classical para meters in the expression for the vacuum energy of the MIT bag for quarks is proposed in the massless case by appealing to the QCD trace anomaly and sc ale separation due to asymptotic freedom. The explicit inclusion of gluons implies an unrealistically low separation scale.
