description | We present an exceptional twin-Higgs model with the minimal symmetry structure for an exact implementation of twin parity along with custodial symmetry. Twin particles are mirrors of the Standard Model yet they carry hypercharge, while the photon is identified with its twin. We thoroughly explore the phenomenological signatures of hypercharged naturalness: long-lived charged particles, a colorless twin top with electric charge 2/3 that once pair-produced, bounds via twin-color interactions and can annihilate to dileptons or a Higgs plus a photon or a Z, and glueballs produced from Higgs decays and twin-quarkonium annihilation that either decay displaced or are stable on collider scales and eventually decay to diphotons. Prospects for detection of these signatures are also discussed. |
