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.
