Abstract

Abstract We re-examine the lower bound on the mass of the Higgs boson, Mh, from Standard Model vaccum stability including next-to-leading-log radiative corrections. This amounts to work with the full one-loop effective potential, V(θ), improved by two-loop RGE, and allows to keep control of the scale invariance of V in a wide range of the θ-field. Our results show that the bound is O (10 GeV) less stringent than in previous estimates. In addition we perform a detailed comparison between the SM lower bounds on Mh and the supersymmetric upper bounds on it. It turns out that depending on the actual value of the top mass, Mt, the eventually measured Higgs mass can discard the pure SM, the Minimal Supersymmetric Standard Model or both.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
