Modular Invariant Soft Breaking, WMAP, Dark Matter and Sparticle Mass Limits
An analysis of soft breaking under the constraint of modular invariance is given. The role of dilaton and moduli dependent front factors in achieving a modular invariant $V_{soft}$ is emphasized. Further, it is shown that in string models $\tan\beta$ is no longer a free parameter but is determined i...
