The original littlest Higgs model with universal fermion couplings is found to be consistent with precision electroweak data but is strongly constrained by Tevatron limits on the predicted centi-weak Z' boson. A possible signal observed by CDF at 240 GeV is consistent with the predicted Z' and a region below 150 GeV is largely unconstrained by collider data.

  1. Heavy Vector Triplets at a Muon Collider

    hep-ph 2026-05 unverdicted novelty 5.0

    Muon colliders can probe heavy vector triplets up to 12 TeV, competitive with HE-LHC but below FCC-hh projections, including indirect electroweak precision limits.
