Based on an explicit model, we propose and discuss the generic features of a possible implementation of the Twin Higgs program in the context of composite Higgs models. We find that the Twin Higgs quadratic divergence cancellation argument can be uplifted to a genuine protection of the Higgs potential, based on symmetries and selection rules, but only under certain conditions which are not fulfilled in some of the existing models. We also find that a viable scenario, not plagued by a massless Twin Photon, can be obtained by not gauging the Twin Hypercharge and taking this as the only source of Twin Symmetry breaking at a very high scale.

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

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

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

Alleviating Cosmological Tensions with the Hadrosymmetric Twin Higgs
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.
