Higgs data constraints on the minimal supersymmetric standard model.

We perform global fits to the most recent data (after summer 2014) on Higgs boson signal strengths in the framework of the minimal supersymmetric standard model. We further impose the existing limits on the masses of charginos, staus, stops, and sbottoms together with the current Higgs mass constraint ∣MH1 - 125.5 GeV∣ < 6 GeV. The heavy supersymmetric (SUSY) particles such as squarks enter into the loop factors of the Hgg and Hyy vertices, while other SUSY particles such as sleptons and charginos also enter into that of the Hyy vertex. We also take into account the possibility of other light particles, such as other Higgs bosons and neutralinos, into which the 125.5 GeV Higgs boson can decay. We use the data from the ATLAS, CMS, and the Tevatron, with existing limits on SUSY particles, to constrain on the relevant SUSY parameters. We obtain allowed regions in the SUSY parameter space of squark, slepton and chargino masses, and the p parameter. We find that [Δ/Sγ/SγSM∣ ≲ 0.1 at 68% confidence level when M-x± > 300 GeV and M-τ1 > 300 GeV, irrespective of the squarks masses. Furthermore, ∣Δγ/SγSM∣ ≲ 0.03 when Mx-±τ1 > 500 GeV and MT1b1 ≳ 600 GeV. [ABSTRACT FROM AUTHOR]
