abstract
LHC-7 has narrowed down the mass range of the light Higgs boson. This result is consistent with the supergravity unification framework, and the current Higgs boson mass window implies a rather significant loop correction to the tree value pointing to a relatively heavy scalar sparticle spectrum with universal boundary conditions. It is shown that the largest value of the Higgs boson mass is obtained on the Hyperbolic Branch of radiative breaking. The implications of light Higgs boson in the broader mass range of 115 GeV to 131 GeV and a narrower range of 123 GeV to 127 GeV are explored in the context of the discovery of supersymmetry at LHC-7 and for the observation of dark matter in direct detection experiments.

Revisiting CMSSM with Non-Universal Gaugino Masses under Current Constraints
Current data restrict the g~-SUGRA scenario to tanβ ≳ 5 and M0 ≳ 20 tanβ GeV, with large muon g-2 contributions difficult and future colliders needed to cover the remaining parameter space.
