abstract

We present a novel framework to solve simultaneously the electroweak hierarchy problem and the strong-CP problem. A small but finite Higgs vacuum expectation value and a small $\theta$-angle are selected after the QCD phase transition, without relying on the Peccei-Quinn mechanism or other traditional solutions. We predict a distinctive pattern of correlated signals at hadronic EDM, fuzzy dark matter and axion experiments.

  1. Why 4D? Spontaneous Dimensional Selection from Gauge Criticality

    hep-ph 2026-07 conditional novelty 7.0 of 10

    Gauge criticality of Yang–Mills, via racetrack confinement and 3D dynamical SUSY breaking, can stabilize radii so that a macroscopic 4D spacetime emerges without being put in by hand.

  2. Probing Quadratically Coupled Ultralight Dark Matter with Pulsar Timing Arrays

    hep-ph 2025-10 conditional novelty 6.0 of 10

    For quadratically coupled ultralight dark matter, pulsar timing arrays can set competitive coherent-signal limits at 10^-24–10^-22 eV, while stochastic-signal limits remain weaker than equivalence-principle constraint...

  3. Minimal Electroweak Baryogenesis via Domain Walls

    hep-ph 2024-12 conditional novelty 6.0 of 10

    Domain wall cores in the minimal Z2-symmetric singlet extension can restore electroweak symmetry and, while sweeping through space, could produce the matter-antimatter asymmetry in a parameter region far lighter and m...

  4. 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.

  5. In Pursuit of New Paradigms: TASI 2024

    hep-ph 2024-12 accept novelty 1.0 of 10

    A review of theoretical paradigms, from pNGB Higgs to SUSY, that attempt to explain the smallness of the Higgs mass.
