The full spectrum of the Littlest Higgs model is analyzed in light of the recent discovery of the Higgs boson mass. We find viable regions in parameter space that are consistent with the standard model.application/pdfen-USLittle HiggsHierarchy problemCollective symmetry breakingLittle Higgs mechanismSimplest Little HiggsLittlest Higgs2013-11-25
