We present a model of electroweak symmetry breaking in which the Higgs boson is a pseudo-Nambu-Goldstone boson. By embedding the standard models SU(2) × U(1) into an SU(4) × U(1) gauge group, one-loop quadratic divergences to the Higgs mass from gauge and top loops are canceled automatically with the minimal particle content. The potential contains a Higgs quartic coupling which does not introduce one-loop quadratic divergences. Our theory is weakly coupled at the electroweak scale, it has new weakly coupled particles at the TeV scale and a cutoff above 10 TeV, all without fine tuning. We discuss the spectrum of the model and estimate the constraints from electroweak precision measurements.

• TeV symmetry and the little hierarchy problem (2003, background): “There are a number of variations of the little Higgs model [17, 18, 19, 20, 21, 22], but in all cases so far the new TeV particles couple directly to the Standard Model particles and one needs to worry about the impact on the precision electroweak physics from these new particles.”
• Theoretical constraints on the Higgs effective couplings (2009, methodology): “The coset space used in majority of the composite Higgs models is symmetric, for which f abc = 0 in the above, except for the little Higgs model based on simple groups [ 27 ].”
