Relic Abundance of LKP Dark Matter in UED model including Effects of Second KK Resonances

Abstract

We reevaluate the thermal relic density of the Kaluza-Klein (KK) dark matter in universal extra dimension models. In particular, we consider the effect of the resonance caused by second KK particles on the density. We find that the annihilation cross sections relevant to the density are significantly enhanced due to the resonance when the Higgs boson mass is large enough (m_h \gtrsim 200 GeV). As a result, the mass of the dark matter particle consistent with the WMAP observation is increased compared to the result which does not include any resonance.
