Multi-Dimensional mSUGRA Likelihood Maps
Abstract
We calculate the likelihood map in the full 7 dimensional parameter space of the minimal supersymmetric standard model (MSSM) assuming universal boundary conditions on the supersymmetry breaking terms. Simultaneous variations of m0, A0, M1/2, tan beta, mt, mb and alpha_s(MZ) are applied using a Markov chain Monte Carlo algorithm. We use measurements of b->s gamma, (g-2)_mu and Omega_{DM} h^2 in order to constrain the model. We present likelihood distributions for some of the sparticle masses, the branching ratio of B_s^0->mu^+ mu^- as well as m_stau-m_{chi_1^0}. The mass ordering allows the important cascade decay squark_L -> chi_2^0 -> slepton_R -> chi_1^0 with a likelihood of 19+/-5%. Excluding the focus point scenario, the pseudoscalar Higgs funnel region has a likelihood of 43+/-4%, the stau coannihilation region has 24+/-6% and the light Higgs pole region has 3+/-1%.Keywords
