We present an updated analysis of the constrained minimal supersymmetricstandard model with mu>0 supplemented by an `asymptotic' Yukawa couplingquasi-unification condition, which allows an acceptable b-quark mass. Imposingconstraints from the cold dark matter abundance in the universe, B physics, themuon anomalous magnetic moment, and the mass m_h of the lightest neutralCP-even Higgs boson, we find that the lightest neutralino cannot act as a colddark matter candidate. This is mainly because the upper bound on the lightestneutralino relic abundance from cold dark matter considerations, despite thefact that this abundance is drastically reduced by neutralino-staucoannihilations, is incompatible with the recent data on the branching ratio ofB_s --> mu^+ mu^-. Allowing for a different particle, such as the axino or thegravitino, to be the lightest supersymmetric particle and, thus, constitute thecold dark matter in the universe, we find that the predicted m_h's in our modelfavor the range (119-126) GeV.
