Multidimensional mSUGRA likelihood maps

We calculate the likelihood map in the full 7-dimensional parameter space of the minimal supersymmetric standard model assuming universal boundary conditions on the supersymmetry breaking terms. Simultaneous variations of m₀, A₀, M1/2, tanβ, mₜ, mb and αₛ(MZ) are applied using a Markov chain Monte Carlo algorithm. We use measurements of b→sγ, (g-2)_μ and ΩDMh² in order to constrain the model. We present likelihood distributions for some of the sparticle masses, for the branching ratio of Bₛ⁰→μ⁺μ^- and for m_τ-m_χ₁⁰. An upper limit of 2×10^-8 on this branching ratio might be achieved at the Tevatron, and would rule out $29%$ of the currently allowed likelihood. If one allows for non-thermal-neutralino components of dark matter, this fraction becomes $35%$. The mass ordering allows the important cascade decay qL→χ₂⁰→lR→χ₁⁰ with a likelihood of 24±4%. The stop-coannihilation region is highly disfavored, whereas the light Higgs region is marginally disfavored.
