Implications of Planck and MAP Measurements On Sparticle Spectra
Abstract
Future sattelite (MAP and Planck) balloon and ground based experiments will the determine the basic cosmological parameters within a few percent. We examine here the effect of this on constraining the SUSY parameter space for supergravity R-parity conserving models (with tanbeta < 25) for the cases of nuCDM and LambdaCDM cosmological models. For the nuCDM (LambdaCDM) models, the gluino mass is restricted by mg~ < 720(540)GeV. In both cases, the cosmological constraints are sensitive to non-universal SUSY soft breaking producing a lower bound mg~ > 400GeV in some regions and for the nuCDM model, gaps in the allowed mg~ range for other regions. For gluino (neutralino) masses greater than 450(65)GeV, m0 is constrained to be small making the quark and slepton mass light generally light and detrmined mostly by mg~.
