摘要：

We combine the constraint suggested by the recent BNL E821 measurement of the anomalous magnetic moment of the muon on the parameter space of the constrained MSSM (CMSSM) with those provided previously by LEP, the measured rate of b --> s gamma decay and the cosmological relic density Omega (chi)h(2). Our treatment of Omega (chi)h(2) includes carefully the direct-channel Higgs poles in annihilation of pairs of neutralinos chi and a complete analysis of chi - (l) over tilde coannihilation. We find excellent consistency between all the constraints for tan B less than or similar to 10 and mu > 0, for restricted ranges of the CMSSM parameters m(0) and m(1/2) All the preferred CMSSM parameter space is within reach of the LHC, but may not be accessible to the Tevatron collider, or to a first-generation e(+) e(-) linear collider with centre-of-mass energy below 1.2 TeV.
