Theoretical study on dimensional deconstruction and little higgs

Abstract

We review the mechanism of dimensional deconstruction. Dimensional deconstruction is useful to make additional dimensions dynamically at low energies where the emerging dimensions are latticized . Fundamental fermion fields live at high energy scales. This fermion fields condensate to meson fields at low energy scales. This meson fields have a Coleman-Weinberg effective potential through the interaction with gauge bosons. And we investigate whether this effective potential has a spontaneous symmetry breaking or not, using the d=5 ring moose model and the d=6 toroidal moose model.
