We present new global fits of the cMSSM, including LHC 1/fb integrated
luminosity SUSY exclusion limits, recent LHC 5/fb constraints on the mass of
the Higgs boson and XENON100 direct detection data. Our analysis fully takes
into account astrophysical and hadronic uncertainties that enter the analysis
when translating direct detection limits into constraints on the cMSSM
parameter space. We provide results for both a Bayesian and a Frequentist
statistical analysis. We find that LHC 2011 constraints in combination with
XENON100 data can rule out a significant portion of the cMSSM parameter space.
Our results further emphasise the complementarity of collider experiments and
direct detection searches in constraining extensions of Standard Model physics.
The LHC 2011 exclusion limit strongly impacts on low-mass regions of cMSSM
parameter space, such as the stau co-annihilation region, while direct
detection data can rule out regions of high SUSY masses, such as the
Focus-Point region, which is unreachable for the LHC in the near future. We
show that, in addition to XENON100 data, the experimental constraint on the
anomalous magnetic moment of the muon plays a dominant role in disfavouring
large scalar and gaugino masses. We find that, should the LHC 2011 excess
hinting towards a Higgs boson at 126 GeV be confirmed, currently favoured
regions of the cMSSM parameter space will be robustly ruled out from both a
Bayesian and a profile likelihood statistical perspective.
