Msugra phenomenology: Current constraints and future prospects

After a short introduction, we delineate regions of the parameter space of the mSUGRA model consistent with theoretical and experimental constraints from (i) direct sparticle searches at LEP 2, (ii) the mass of the lightest Higgs scalar, (iii) the recent determination of the cold dark matter density by the WMAP collaboration, (iv) the anomalous magnetic moment of the muon, and (v) limits on the branching fractions for the flavour-violating decays B --> X(s)gamma and B-s --> mu(+)mu(-). We comment on the relative robustness of various constraints, and then discuss prospects for SUSY searches for these allowed parameter ranges. We then consider models with small deviations from mass universality that is the hallmark of the mSUGRA framework, and consider how these might be probed via precision experiments at linear colliders.
