We construct an extension of the MSSM in which superpartners can naturally be heavier than the electroweak scale. This ``little hierarchy'' of scales is stable because the Higgs arises as a pseudo-Nambu-Goldstone boson in the breaking of an accidental SU(4) symmetry of the Higgs sector. Supersymmetry and the global symmetry combine to forbid logarithmically divergent one-loop contributions to the Higgs mass. The accidental symmetry follows from a simple ``twin'' parity which exchanges the SU(2) sectors in the SU(3)_C x SU(2)_L x SU(2)_R x U(1)_X gauge group.

  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. Freeze-Twin Dark Matter

    hep-ph 2019-08 conditional novelty 6.0 of 10

    Twin electrons and positrons, frozen in via a massive twin photon, can be the dark matter in mirror twin Higgs models with asymmetric reheating, with the required kinetic mixing matching loop-level expectations.

  3. 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.
