Global fits of the Non-Universal Higgs Model

We carry out global fits to the Non-Universal Higgs Model (NUHM), applying all relevant present-day constraints. We present global probability maps for the NUHM parameters and observables (including collider signatures, direct and indirect detection quantities), both in terms of posterior probabilities and in terms of profile likelihood maps. We identify regions of the parameter space where the neutralino dark matter in the model is either bino-like, or else higgsino-like with mass close to 1 TeV and spin-independent scattering cross section ~ 10^{-9}-10^{-8} pb. We trace the occurrence of the higgsino-like region to be a consequence of a mild focusing effect in the running of one of the Higgs masses, the existence of which in the NUHM we identify in our analysis. Although the usual bino-like neutralino is more prominent, higgsino-like dark matter cannot be excluded, however its significance strongly depends on the prior and statistics used to assess it. We note that, despite experimental constraints often favoring different regions of parameter space to the Constrained MSSM, most observational consequences appear fairly similar, which will make it challenging to distinguish the two models experimentally
