Abstract

Global frequentist fits to the CMSSM and NUHM1 using the MasterCode framework predicted M _h≃119 GeV in fits incorporating the (g−2)_μ constraint and ≃126 GeV without it. Recent results by ATLAS and CMS could be compatible with a Standard Model-like Higgs boson around M _h≃125 GeV. We use the previous MasterCode analysis to calculate the likelihood for a measurement of any nominal Higgs mass within the range of 115 to 130 GeV. Assuming a Higgs mass measurement at M _h≃125 GeV, we display updated global likelihood contours in the (m ₀,m _1/2) and other parameter planes of the CMSSM and NUHM1, and present updated likelihood functions for $m_{\tilde{g}}, m_{\tilde{q}_{R}}$ , BR(B _s→μ ⁺ μ ⁻) and the spin-independent dark matter cross section $\sigma^{\mathrm{SI}}_{p}$ . The implications of dropping (g−2)_μ from the fits are also discussed. We furthermore comment on a hypothetical measurement of M _h≃119 GeV.
