摘要：

我们对非普适希格斯模型（NUHM）进行了全局拟合，应用了所有相关的现代约束。我们提出了全球概率图NUHM参数和可观的（包括对撞机签名，直接和间接的检测量），无论是在后验概率和配置文件的似然图。我们确定了模型中中性伴子暗物质的参数空间区域，在这些区域中，中性伴子暗物质要么是类双星，要么是类希格斯诺，质量接近1 TeV，与自旋无关的散射截面约为10^{-9}-10 ^{-8} pb。我们跟踪的希格斯诺样区域的发生是一个温和的聚焦效应在运行的希格斯质量之一，在NUHM中，我们在我们的分析中确定的存在的后果。尽管通常的类双中性伴子更为突出，但类希格斯诺暗物质也不能排除，然而其重要性强烈依赖于用于评估它的先验和统计。我们注意到，尽管实验约束往往有利于与约束MSSM不同的参数空间区域，但大多数观测结果似乎相当相似，这将使区分这两个模型的实验挑战

英文摘要：

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
