Title: Supersymmetric Little-Higgs

Abstract: In the run up to LHC most theoretical models of the origin of the electroweak symmetry breaking scale appear fine-tuned. In the case of supersymmetry, this is due to non-observation of superpartners and the Higgs at LEP and the Tevatron. In the case of little-Higgs models (where Higgs boson arises as a pseudo-Goldstone boson of a spontaneously broken global symmetry), this is due to the effects on electroweak precision observables. In this talk I will show how a combination of supersymmetry and little-Higgs mechanism can lead to successful models of electroweak symmetry breaking without fine-tuning.
