On the Higgs mass in the CMSSM

We estimate the mass of the lightest neutral Higgs boson h in the minimal supersymmetric extension of the Standard Model with universal soft supersymmetry-breaking masses (CMSSM), subject to the available accelerator and astrophysical constraints. For mt=174.3GeV, we find that 114GeV119GeV may correspond to much larger values of m1/2 and A0, lying in rapid-annihilation funnels. The favoured ranges of mh vary with mt, the two peaks being more clearly separated for mt=178GeV and merging for mt=172.7GeV. If the gμ−2 constraint is imposed, the mode of the mh distribution is quite stable, being ∼117GeV for all the studied values of mt.
