The NUHM2 after LHC Run 1

We make a frequentist analysis of the parameter space of the NUHM2, in which the soft supersymmetry (SUSY)-breaking contributions to the masses of the two Higgs multiplets, $$m^2_{H_{u,d}}$$, vary independently from the universal soft SUSY-breaking contributions $$m^2_0$$ to the masses of squarks and sleptons. Our analysis uses the MultiNest sampling algorithm with over $$4 \times 10^8$$ points to sample the NUHM2 parameter space. It includes the ATLAS and CMS Higgs mass measurements as well as the ATLAS search for supersymmetric jets + $${/\!\!E}_T$$ signals using the full LHC Run 1 data, the measurements of $$\mathrm{BR}(B_s \rightarrow \mu ^+\mu ^-)$$ by LHCb and CMS together with other B-physics observables, electroweak precision observables and the XENON100 and LUX searches for spin-independent dark-matter scattering. We find that the preferred regions of the NUHM2 parameter space have negative SUSY-breaking scalar masses squared at the GUT scale for squarks and sleptons, $$m_0^2 < 0$$, as well as $$m^2_{H_u} < m^2_{H_d} < 0$$. The tension present in the CMSSM and NUHM1 between the supersymmetric interpretation of $$(g-2)_\mu $$ and the absence to date of SUSY at the LHC is not significantly alleviated in the NUHM2. We find that the minimum $$\chi ^2 = 32.5$$ with 21 degrees of freedom (dof) in the NUHM2, to be compared with $$\chi ^2/\mathrm{dof} = 35.0/23$$ in the CMSSM, and $$\chi ^2/\mathrm{dof} = 32.7/22$$ in the NUHM1. We find that the one-dimensional likelihood functions for sparticle masses and other observables are similar to those found previously in the CMSSM and NUHM1
