We discuss the allowed parameter spaces of supersymmetric scenarios in lightof improved Higgs mass predictions provided by FeynHiggs 2.10.0. The Higgs masspredictions combine Feynman-diagrammatic results with a resummation of leadingand subleading logarithmic corrections from the stop/top sector, which yield asignificant improvement in the region of large stop masses. Scans in the pMSSMparameter space show that, for given values of the soft supersymmetry-breakingparameters, the new logarithmic contributions beyond the two-loop orderimplemented in FeynHiggs tend to give larger values of the light CP-even Higgsmass, M_h, in the region of large stop masses than previous predictions thatwere based on a fixed-order Feynman-diagrammatic result, though the differencesare generally consistent with the previous estimates of theoreticaluncertainties. We re-analyze the parameter spaces of the CMSSM, NUHM1 andNUHM2, taking into account also the constraints from CMS and LHCb measurementsof B_s to \mu+\mu- and ATLAS searches for MET events using 20/fb of LHC data at8 TeV. Within the CMSSM, the Higgs mass constraint disfavours tan beta lesssim10, though not in the NUHM1 or NUHM2.
