Emergence of the electroweak scale through the Higgs portal

摘要: Having discovered a candidate for the final piece of Standard Model, Higgs boson, question remains why its vacuum expectation value and mass are so much smaller than Planck scale (or any other high new physics). One elegant solution was provided by Coleman Weinberg, where all scales generated from dimensionless coupling constants via dimensional transmutation. However, original Coleman-Weinberg scenario predicts which is too light; it parametrically suppressed compared to vectors bosons, hence lighter observed value. In this paper we argue that scale, mechanism in hidden sector then transmitted Model through portal, can naturally explain smallness electroweak UV cutoff at same time be consistent with We analyse phenomenology such model context present future colliders low energy measurements.
