Abstract
Using a simple numerical method, we compute the: stability of the MSSM vacu um with respect to tunneling. The stability criterion is then used to put r estrictions on the mass parameters. These restrictions are necessary condit ions for the vacuum stability and complement the existing sufficiency condi tions obtained analytically. (C) 1999 Published by Elsevier Science B.V.
