Abstract




We update previous frequentist analyses of the CMSSM and NUHM1 parameter spaces to include the public results of searches for supersymmetric signals using similar to 1/fb of LHC data recorded by ATLAS and CMS and similar to 0.3/fb of data recorded by LHCb in addition to electroweak precision and Bphysics observables. We also include the constraints imposed by the cosmological dark matter density and the XENON100 search for spinindependent dark matter scattering. The LHC data set includes ATLAS and CMS searches for jets + (sic)(T) events and for the heavier MSSM Higgs bosons, and the upper limits on BR(Bs > mu(+)mu()) from LHCb and CMS. The absences of jets + (sic)(T) 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 similar to 40, a possibility that is, however, under pressure from heavy Higgs searches and the upper limits on BR(Bs > mu(+)mu()). As a result, the pvalue for the CMSSM fit is reduced to similar to 15(38)%, and that for the NUHM1 to similar to 16(38)%, to be compared with similar to 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. We discuss the sensitivities of the fits to the (g  2)(mu) and BR(b > s gamma) constraints, contrasting fits with and without the (g  2)(mu) constraint, and combining the theoretical and experimental errors for BR(b > s gamma) linearly or in quadrature. We present predictions for m((g) over tilde), BR(Bs > mu(+)mu()), Mh and MA, and update predictions for spinindependent dark matter scattering, incorporating the uncertainty in the pnucleon sigma term Sigma(pi N).
