Description
Models with Universal Extra Dimensions provide one of the simplest extra dimensional extensions of the Standard Model which incorporates a dark matter candidate and can provide a rich LHC phenomenology which strongly resembles SUSY signals. The minimal UED Kaluza Klein Spectrum can be modified in two ways: by operators which are localized at the orbifold fixed points (non-minimal UED) or by five-dimensional fermion mass terms (split UED). We show that and how both these options strongly modify the electroweak precision constraints on UED.
