Bosonic supersymmetry and KK dark matter

TH Auditorium (CERN)

In this talk I will review recent progress on the phenomenology of "bosonic supersymmetry", a.k.a. Universal Extra Dimensions. First I will show the effect of the radiative corrections on the mass spectrum and decay properties of the Kaluza-Klein (KK) particles and will discuss the discovery reach at the Tevatron and the LHC. In minimal UED models the collider signatures of the first level of KK particles are very similar to supersymmetry with a stable neutralino LSP, presenting a challenge for their interpretation. In the second half of the talk I will discuss KK dark matter. If the standard model particles propagate in extra dimensions and Kaluza-Klein parity is conserved, the lightest KK particle (LKP) is an excellent dark matter candidate. I will discuss the prospects for direct and indirect detection of KK dark matter, again drawing several comparisons to the familiar case of SUSY dark matter. The talk is based on hep-ph/0204342, hep-ph/0205314 and hep-ph/0207125.
