Supersymmetry in Light of 1/fb of LHC Data
We update previous frequentist analyses of the CMSSM and NUHM1 parameter spaces to include the public results of searches for supersymmetric signals using ~1 /fb of LHC data recorded by ATLAS and CMS and ~0.3/fb of data recorded by LHCb in addition to electroweak precision and B-physics observables. We also include the constraints imposed by the cosmological dark matter density and the XENON100 search for spin-independent dark matter scattering. The LHC data set includes ATLAS and CMS searches for jets + missing ET events and for the heavier MSSM Higgs bosons, and the upper limits on B_s to mu^+ mu^- from LHCb and CMS. The absences of jets + missing ET signals in the LHC data favour heavier mass spectra than in our previous analyses of the CMSSM and NUHM1, which may be reconciled with (g-2)_mu if tan beta ~ 40, a possibility that is however under pressure from heavy Higgs searches and the upper limits on B_s to mu^+ mu^-. As a result, the p-value for the CMSSM fit is reduced to ~ 15 (38)%, and that for the NUHM1 to ~ 16 (38)%, to be compared with ~ 9 (49)% for the Standard Model limit of the CMSSM for the same set of observables (dropping (g-2)_mu), ignoring the dark matter relic density in both cases. We discuss the sensitivities of the fits to the (g-2)_mu and b to s gamma constraints, contrasting fits with and without the (g-2)_mu constraint, and combining the theoretical and experimental errors for b to s gamma linearly or in quadrature. We present predictions for m_gluino, B_s to mu^+ mu^-, M_h and M_A, and update predictions for spin-independent dark matter scattering, stressing again the importance of taking into account the uncertainty in the pi-nucleon sigma term, Sigma_{pi N}. Finally, we present predictions based on our fits for the likely thresholds for sparticle pair production in e^+e^- collisions in the CMSSM and NUHM1.
