"Cosmology and Collider Searches in GUT-less SUSY Scenarios"

Abstract

TeV scale supersymmetry offers a compelling solution to the related hierarchy and naturalness problems of the Standard Model of particle physics. If R-parity is conserved, the lightest supersymmetric particle is stable, and, if uncharged, is therefore a natural particle candidate for astrophysical cold dark matter. I will give a brief overview of neutralino dark matter in the Constrained Minimal Supersymmetric Standard Model (CMSSM), then I will discuss the impact of deviations from this scenario in which supersymmetry breaking appears at a scale below the supersymmetric grand unification scale. The constraint on the relic density of neutralinos and prospects for direct detection of neutalino dark matter will be discussed, as well as discovery potentials in such scenarios at both the LHC and at a future linear electron-positron collider.
