2 00 4 A Not So Little Higgs ?

Most recent models assuming the Higgs Boson is a pseudo-Nambu-Goldstone Boson (pNGb) are motivated by the indication from Standard Model fits that its mass is ≤ 200GeV .Starting from a modified SM. of Forshaw et. al. with a triplet boson added and a heavier Higgs Boson, we consider a pNGb model.This differs in several ways from most little Higgs models: apart from using only one loop, the cutoff scale is reduced to 5 TeV, and consequently a linear sigma model is used to alleviate FCNC effects; no new vector bosons are required, but vector-like isosinglet fermions are needed, but play no part in determining the mass of the Higgs boson.The phenomenology of the isosinglet pNGb that arises from the SU (3) × SU (3) → SU (3) model we use is briefly discussed. Some potential theoretical and phenomenological problems are mentioned briefly.
