Double protection of the Higgs potential in a supersymmetric little Higgs model.
A mechanism of double protection of the Higgs potential, by supersymmetry and by a global symmetry, is investigated in a class of supersymmetric models with the SU(3)cxSU(3)wxU(1)x gauge symmetry. The electroweak symmetry can be then broken with no fine-tuning at all.
