abstract

We construct a UV completion of the relaxion in a warped extra dimension. We identify the relaxion with the zero mode of the fifth component of a bulk gauge field and show how hierarchically different decay constants for this field can be achieved by different localizations of anomalous terms in the warped space. This framework may also find applications for other axion-like fields. The cutoff of the relaxion model is identified as the scale of the IR brane where the Higgs lives, which can be as high as $10^6$ GeV, while above this scale warping takes over in protecting the Higgs mass.

  1. Vacuum Metastability from Axion-Higgs Criticality

    hep-ph 2024-12 conditional novelty 6.0 of 10

    An ALP-Higgs coupling can lower the vacuum instability scale to near the weak scale, predicting an axion-like particle between 1 MeV and 20 GeV that future experiments can fully probe.

  2. Wiggly dilaton: a landscape of spontaneously broken scale invariance

    hep-th 2024-11 conditional novelty 6.0 of 10

    A 5D axion-like field with periodic brane potentials gives the dilaton a wiggly potential with multiple vacua, enabling relaxion-like or light-dilaton scenarios at the cost of fine-tuning.
