The CMS Collaboration has released the results of its search forsupersymmetry, by applying an alphaT method to 1.1/fb of data at 7 TeV. Thenull result excludes (at 95% CL) a low-mass region of the Constrained MSSM'sparameter space that was previously favored by other experiments. Additionally,the negative result of the XENON100 dark matter search has excluded (at 90% CL)values of the spin-independent scattering cross sections sigma^SI_p as low as10^-8 pb. We incorporate these improved experimental constraints into a globalBayesian fit of the Constrained MSSM by constructing approximate likelihoodfunctions. In the case of the alphaT limit, we simulate detector efficiency forthe CMS alphaT 1.1/fb and validate our method against the official 95% CLcontour. We identify the 68% and 95% credible posterior regions of the CMSSMparameters, and also find the best-fit point. We find that the credible regionschange considerably once a likelihood from alphaT is included, in particularthe narrow light Higgs resonance region becomes excluded, but the focuspoint/horizontal branch region remains allowed at the 1sigma level. Adding thelimit from XENON100 has a weaker additional effect, in part due to largeuncertainties in evaluating sigma^SI_p, which we include in a conservative way,although we find that it reduces the posterior probability of the focus pointregion to the 2sigma level. The new regions of high posterior favor squarkslighter than the gluino and all but one Higgs bosons heavy. The dark matterneutralino mass is found in the range 250 GeV <~ m_Chi1 <~ 343 GeV (at 1sigma)while, as the result of improved limits from the LHC, the favored range ofsigma^SI_p is pushed down to values below 10^{-9} pb. We highlight tensionbetween (g-2)_mu and BR(b->sg), which is exacerbated by including the alphaTlimit; each constraint favors a different region of the CMSSM's massparameters.
