Implications of Planck and MAP Measurements On Sparticle Spectra

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 m_g~ < 720(540)GeV. In both cases, the cosmological constraints are sensitive to non-universal SUSY soft breaking producing a lower bound m_g~ > 400GeV in some regions and for the nuCDM model, gaps in the allowed m_g~ range for other regions. For gluino (neutralino) masses greater than 450(65)GeV, m_0 is constrained to be small making the quark and slepton mass light generally light and detrmined mostly by m_g~.
