We explore the consequences of an electroweak symmetry breaking sector whichexhibits approximately scale invariant dynamics -- i.e., nontrivial fixed pointbehavior, as in unparticle models. One can think of an unHiggs as a compositeHiggs boson with a continuous mass distribution. We find it convenient torepresent the unHiggs in terms of a Kallen-Lehmann spectral function, fromwhich it is simple to verify the generation of gauge boson and fermion masses,and unitarization of WW scattering. We show that a spectral function with broadsupport, which corresponds to approximate fixed point behavior over an extendedrange of energy, can lead to an effectively invisible Higgs particle, whosedecays at LEP or LHC could be obscured by background.
