摘要：
We show that, for all values of Tan beta and the light right-handed stop mass for which the electroweak phase transition is strong enough to avoid washout following electroweak baryogenesis, the electroweak vacuum is stable over the lifetime of the observed Universe. Cosmological stability of the electroweak vacuum is violated only if the light right-handed stop is Lighter than 100-115 GeV. (C) 1997 Elsevier Science B.V.
