Query: A heavy little Higgs and a light Z' under the radar   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.
