The Littlest Higgs

  title={The Littlest Higgs},
  author={Littlest Higgs and Nima Arkani-Hamed},
We present an economical theory of natural electroweak symmetry breaking, generalizing an approach based on deconstruction. This theory is the smallest extension of the Standard Model to date that stabilizes the electroweak scale with a naturally light Higgs and weakly coupled new physics at TeV energies. The Higgs is one of a set of pseudo Goldstone bosons in an SU(5)/SO(5) nonlinear sigma model. The symmetry breaking scale f is around a TeV, with the cutoff Λ<∼ 4πf ∼ 10 TeV. A single… CONTINUE READING
