We examine the parameter space of the constrained MSSM by considering various experimental constraints. For the dark matter sector, we require the neutralino dark matter to account for the relic density measured by the WMAP and satisfy the XENON limits on its scattering rate with the nucleon. For the collider constraints, we consider all relevant direct and indirect limits from LEP, Tevatron and LHC as well as the muon anomalous magnetic moment. Especially, for the limits from B-s -> mu(+)mu(-), we either directly consider its branching ratio with the latest LHC data or alternatively consider the double ratio of the purely leptonic decays defined by Br(B-s -> mu(+)mu(-))/Br(B-mu -> tau nu(tau))/Br(D-s -> tau nu(tau))/Br(D -> tau mu(tau)). We find that under these constraints, the mass of the lightest Higgs boson (h) in both the CMSSM and the NUHM2 is upper bounded by about 124 GeV (126 GeV) before (after) considering its theoretical uncertainty. We also find that for these models the di-photon Higgs signal at the LHC is suppressed relative to the SM prediction, and that the lower bound of the top-squark mass goes up with nth. reaching 600 GeV for m(h) = 124 GeV.

The possibility of describing the LHC observations in the context of the MSSM has been explored in numerous papers, including [3][4][5][6][7][8][9]. A general conclusion seems to be that if all the constraints noted above, including a and 2h, ”
Higgs Bosons Near 125 GeV in the NMSSM with Constraints at the GUT Scale (2012, methodology): “We find that one should allow for deviations from full universality in the Higgs sector, both for the NMSSM-specific soft Susy breaking terms and the MSSM-like Higgs soft masses like in the MSSM studies in [8, 11, 17, 20].”
On naturalness of the MSSM and NMSSM (2012, background): “• The discovery of the relatively heavy Higgs boson and the null XENON100 experimental result [28] place the neutralino LSP DM candidate in an unsatisfying position [24–26].”
Interpreting LHC Higgs results from natural new physics perspective (2012, background): “A number of partly overlapping papers have recently investigated the 125 GeV Higgs-like excess in the context of composite Higgs [16], supersymmetric Higgs [17–28], and multi-Higgs models [29–32]; see also [33–41].”
Reconstructing Higgs boson properties from the LHC and Tevatron data (2012, methodology): “Supersymmetric theories that attempt to solve the naturalness problem of the electroweak scale have been stringently constrained by the LHC direct searches as well as by the Higgs boson results [58, 83–113].”
