Neutralino Relic Density with a Cosmological Constant confronts Electroweak Precision Measurements


We discuss the relic density of the lightest of the supersymmetric particles (LSP) in view of new cosmological data, which favour the concept of an accelerating Universe with a non-vanishing cosmological constant. The new bound on the Cold Dark Matter density, ΩCDMh 2 0 . 0.22, puts stringent constraints on supersymmetry preferring low supersymmetry… (More)
