A little Higgs model with exact dark matter parity

Based on a recent idea by Krohn and Yavin, we construct a little Higgs modelwith an internal parity that is not broken by anomalous Wess-Zumino-Wittenterms. The model is a modification of the "minimal moose" models byArkani-Hamed et al. and Cheng and Low. The new parity prevents largecorrections to oblique electroweak parameters and leads to a viable dark mattercandidate. It is shown how the complete Standard Model particle content,including quarks and leptons together with their Yukawa couplings, can beimplemented. Successful electroweak symmetry breaking and consistency withelectroweak precision constraints is achieved for natural paramters choices. Arich spectrum of new particles is predicted at the TeV scale, some of whichhave sizable production cross sections and striking decay signatures at theLHC.Comment: 25 pp. LaTeX; v2: improved discussion of precision constraints and references added; v3: summary of model structure added at beginning of sect. 2, version published in JHEP; v4: small correction in Fig.5; v5: correction to Fig.
