We present a model of electroweak symmetry breaking in which the Higgs bosonis a pseudo-Nambu-Goldstone boson. By embedding the standard model SU(2) x U(1)into an SU(4) x U(1) gauge group, one-loop quadratic divergences to the Higgsmass from gauge and top loops are canceled automatically with the minimalparticle content. The potential contains a Higgs quartic coupling which doesnot introduce one-loop quadratic divergences. Our theory is weakly coupled atthe electroweak scale, it has new weakly coupled particles at the TeV scale anda cutoff above 10 TeV, all without fine tuning. We discuss the spectrum of themodel and estimate the constraints from electroweak precision measurements.Comment: 29 pages, referencing error corrected after death threats, dude remove
