Description

We present a new Little Higgs model, motivated by the deconstruction of a five- dimensional gauge-Higgs model. The approximate global symmetry is SO(5) x SO(5), breaking to SO(5), with a gauged subgroup of SU(2) x SU(2) x SU(2) x U(1), breaking to SU(2)L x U(1)Y. Radiative corrections produce an additional small vacuum misalignment, breaking the electroweak symmetry down to U(1)em. Features of this model are: the only un-eaten pseudo-Goldstone boson is the Higgs boson; the model contains a custodial symmetry, which ensures that T=0 at tree-level; and the potential for the Higgs boson is generated entirely through one-loop radiative corrections; the model predicts a light Higgs boson mass, which is strongly correlated with the masses of the two heavy top quark partners. The electroweak constraints at one-loop order are also considered.
