Résumé:

We present an updated analysis of the present constraints on the parameter space of the minimal supergravity model (mSUGRA). New features include, in particular, an improved calculation of the masses of neutral Higgs bosons, constraints from $b \rightarrow s l+ l-$ decays, and updated $g_\mu-2$ constraints. We focus on the minimal allowed masses of sparticles and Higgses from various sets of constraints. We find that the direct experimental limits from collider and Dark Matter searches can still be saturated in many cases within this model, even after the quite restrictive WMAP constraint on the Dark Matter relic density. Consequences for sparticle production at the International Linear Collider in this scenario are briefly discussed.
