Electroweak precision data and gravitino dark matter
Description
Electroweak precision measurements can provide indirect information about the possible scale of supersymmetry already at the present level of accuracy. We review present day sensitivities of precision data in mSUGRA-type models with the gravitino as the lightest supersymmetric particle (LSP). The x2 fit is based on Mw, sin2θeff, (g-2)μ, BR(b → sγ) and the lightest MSSM Higgs boson mass, Mh. We find indications for relatively light soft supersymmetry-breaking masses, offering good prospects for the LHC and the ILC, and in some cases also for the Tevatron. (author)
