Abstract

We assume the validity of the standard model up to an arbitrary high-energy scale and discuss what information on the early stages of the Universe can be extracted from a measurement of the Higgs mass. For , the Higgs potential can develop an instability at large-field values. From the absence of excessive thermal Higgs field fluctuations we derive a bound on the reheat temperature after inflation as a function of the Higgs and top masses. Then we discuss the interplay between the quantum Higgs fluctuations generated during the primordial stage of inflation and the cosmological perturbations, in the context of landscape scenarios in which the inflationary parameters scan. We show that, within the large-field models of inflation, it is highly improbable to obtain the observed cosmological perturbations in a Universe with a light Higgs. Moreover, independently of the inflationary model, the detection of primordial tensor perturbations through the B mode of CMB polarization and the discovery of a light Higgs can simultaneously occur only with exponentially small probability, unless there is new physics beyond the standard model.

  • For the observed values of the Standard Model parameters, thermal corrections do not destabilise the electroweak vacuum, even when the reheating temperature is close to the Planck scale.

    “For the observed values of the SM parameters, the latter effect is dominant and thermal corrections do not destabilise the electroweak vacuum, even when the reheating temperature is close to the Planck scale [14].”

    From The cosmological Higgstory of the vacuum instability (2015) · cites this paper as [14]

    The discussion following equation (12) in section 3 says the electroweak vacuum is sufficiently long-lived even at temperatures around the Planck mass when the Higgs mass exceeds a threshold that depends on other Standard Model parameters. The paper does not establish that the observed parameter values satisfy that condition, so it supports the thermal-stability result conditionally rather than for the observed values as stated.

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.
