Upper limits on sparticle masses from WMAP dark matter constraints with modular invariant soft breaking

An analysis of dark matter within the framework of modular invariant soft breaking is given. In such scenarios inclusion of the radiative electroweak symmetry breaking constraint determines $\tan\beta$ which leads to a more constrained analysis. It is shown that for $\mu$ positive for this constrained system the WMAP data leads to upper limits on sparticle masses that lie within reach of the LHC with also the possibility that some sparticles may be accessible at RUNII of the Tevatron.
