We present a general class of natural theories in which the Higgs is a pseudo-goldstone boson in an orbifolded gauge theory. The symmetry protecting the Higgs at low energies is an accidental global symmetry of the quadratic action, rather than a full continuous symmetry. The lightest degrees of freedom protecting the weak scale carry no Standard Model (SM) quantum numbers and interact with visible matter principally through the Higgs portal. We find that the twin Higgs is the simplest example of an orbifold Higgs. This opens the door to the systematic study of "neutral naturalness": natural theories with SM-neutral states that are as yet untested by the LHC.

  1. Long-Lived Dark Hadrons at the Electron-Ion Collider

    hep-ph 2026-07 conditional novelty 6.0 of 10

    A benchmark dark-QCD model with long-lived dark pions mixing into an axion-like state could let the EIC probe electron-portal couplings and dark pion masses beyond the reach of B-factories.

  2. Dark Photons and Gravitino Like Particles: Complete EFT Operator Basis

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A new on-shell method using Young tableaux constructs complete EFT operator bases for massive particles of any spin, applied to dark photons and spin-3/2 gravitino-like particles up to dimension 8.

  3. Nelson-Barr ultralight dark matter

    hep-ph 2024-05 unverdicted novelty 6.0 of 10

    Nelson-Barr mechanism yields ultralight scalar dark matter inducing time-periodic variation in CKM matrix elements, distinguishable from QCD axion and detectable via nuclear clocks.

  4. Dark photons and axion-like particles at the Electron-Ion Collider in China

    hep-ph 2024-12 conditional novelty 5.0 of 10

    Projected EicC searches could probe dark photons from about 1 MeV to 3 GeV and photon-coupled axion-like particles from 0.1 to 5 GeV, covering parameter space not yet excluded by other experiments.

  5. Alleviating Cosmological Tensions with the Hadrosymmetric Twin Higgs

    astro-ph.CO 2025-10 reject novelty 4.0 of 10

    The HTH cosmology fit yields a negligible twin-pion decay rate and density, so the reported H0-tension relief is an artifact of widened parameter errors rather than a new physical mechanism.
