The CMSSM and NUHM1 in light of 7 TeV LHC, B_s→μ⁺μ^- and XENON100 data

We make a frequentist analysis of the parameter space of the CMSSM and NUHM1, using a Markov Chain Monte Carlo (MCMC) with 95 (221) million points to sample the CMSSM (NUHM1) parameter spaces. Our analysis includes the ATLAS search for supersymmetric jets + E_T signals using ~5/fb of LHC data at 7 TeV, which we apply using PYTHIA and a Delphes implementation that we validate in the relevant parameter regions of the CMSSM and NUHM1. Our analysis also includes the constraint imposed by searches for BR(B_s→μ⁺μ^-) by LHCb, CMS, ATLAS and CDF, and the limit on spin-independent dark matter scattering from 225 live days of XENON100 data. We assume M_h~125 GeV, and use a full set of electroweak precision and other flavour-physics observables, as well as the cold dark matter density constraint. The ATLAS_5/fb constraint has relatively limited effects on the 68 and 95 % CL regions in the (m₀,m_1/2) planes of the CMSSM and NUHM1. The new BR(B_s→μ⁺μ^-) constraint has greater impacts on these CL regions, and also impacts significantly the 68 and 95 % CL regions in the (M_A,tanβ) planes of both models, reducing the best-fit values of tanβ. The recent XENON100 data eliminate the focus-point region in the CMSSM and affect the 68 and 95 % CL regions in the NUHM1. In combination, these new constraints reduce the best-fit values of m₀,m_1/2 in the CMSSM, and increase the global χ² from 31. 0 to 32. 8, reducing the p-value from 12 % to 8. 5 %. In the case of the NUHM1, they have little effect on the best-fit values of m₀,m_1/2, but increase the global χ² from 28. 9 to 31. 3, thereby reducing the p-value from 15 % to 9. 1 %.
