Abstract
We discuss renormalisation-group improvement of the effective potentia l both in general and in the context of O(N) scalar phi4 and the Stand ard Model. In the latter case we find that absolute stability of the e lectroweak vacuum implies that m(H) greater-than-or-equal-to 1.95m(t) - 189 GeV, for alpha3(M(Z)) = 0.11. We point out that the lower bound on m(H) decreases if alpha3(M(Z)) is increased.
