Abstract
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, m2
Hu,d
, vary independently from the universal
soft SUSY-breaking contributions m2
0 to the masses
of squarks and sleptons. Our analysis uses the MultiNest
sampling algorithm with over 4 × 108 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 BR(Bs → μ+μ−) 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, m2
0 < 0, as well
as m2
Hu < m2
Hd < 0. The tension present in the CMSSM
and NUHM1 between the supersymmetric interpretation of
(g − 2)μ and the absence to date of SUSY at the LHC is
not significantly alleviated in the NUHM2. We find that the
minimum χ2 = 32.5 with 21 degrees of freedom (dof) in
the NUHM2, to be compared with χ2/dof = 35.0/23 in
the CMSSM, and χ2/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.
