Minimal universal extra dimensions (mUED) is often thought to predict that the lightest Kaluza-Klein particle (LKP) is the Kaluza-Klein gauge boson B^1, leading to conventional missing energy signals at colliders and WIMP dark matter. In…

In universal extra dimension (UED) models with one compactified extra dimension, a Z_2 symmetry, termed KK-parity, ensures the stability of the lightest Kaluza-Klein particle (LKP). This symmetry leads to two fixed points. In non-minimal…
We construct models with a Kaluza-Klein (KK) parity in a five- dimensional warped geometry, in an attempt to address the little hierarchy problem present in setups with bulk Standard Model fields. The lightest KK particle (LKP) is stable…
