| Résumé : | We study the complementarity between dark matter experiments (direct detection and indirect detection) and accelerator experiments (the CERN LHC and a √s = 1 TeV e+e- linear collider) within the framework of the constrained minimal supersymmetric standard model (MSSM). We show how non-universality in the scalar and gaugino sectors can affect the experimental prospects to discover the supersymmetric particles. The future experiments will explore a large part of the parameter space of the MSSM favored by the Wilkinson Microwave Anisotropy Probe (WMAP) constraint on the relic density, but there still exist some regions beyond reach for certain extreme (fine tuned) values of the supersymmetric parameters. Whereas the focus point region characterized by heavy scalars will be easily probed by experiments searching for dark matter, the regions with heavy gauginos and light sfermions will be accessible more easily by collider experiments. More information on both supersymmetry and astrophysics parameters can thus be obtained by combining the different signals. © Springer-Verlag Berlin Heidelberg 2007. |
