Abstract
New data on the anomalous magnetic moment of the muon together with the b - -> X(s)gamma decay rate are considered within the supergravity inspired con strained minimal supersymmetric model. We perform a global statistical chi (2) analysis of these data and show that the allowed region of parameter sp ace is bounded from below by the Higgs limit, which depends on the trilinea r coupling and from above by the anomalous magnetic moment a(mu). The newes t b --> X(s)gamma data deviate 1.7 sigma from recent SM calculations and pr efer a similar parameter region as the 2.6 sigma deviation from a(mu). (C) 2001 Elsevier Science B.V.
