摘要：
The effective potential for radiatively broken electroweak symmetry in the single-Higgs-doublet standard model is explored to four sequentially subleading logarithm-summation levels (5-loops) in the dominant Higgs self-interaction couplant lambda. We augment these results with all contributing leading logarithms in the remaining large but subdominant standard model couplants [t-quark, QCD and SU(2)circle times U(1) gauge couplants] as well as next to leading-logarithm contributions from the largest of these, the t-quark and QCD couplants. Order-by-order stability is demonstrated for earlier leading-logarithm predictions of an O (220 GeV) Higgs boson mass in conjunction with fivefold enhancement of the value for lambda over that anticipated from conventional spontaneous symmetry breaking.
