标题： Higgs boson in a flavor-extension of the CMSSM

摘要： 希格斯玻色子与停止子和超魅力夸克之间的味破坏耦合可能非常重要，因为除了将希格斯玻色子的质量提升几GeV外，它还可能在显著降低超对称破缺尺度方面发挥关键的物理作用。在本工作中，我们研究了这种味破坏耦合在约束最小超对称标准模型（CMSSM）框架下对LEP数据、LHC上的希格斯数据、精确可观测量以及暗物质残留密度的影响，使用贝叶斯统计方法。我们的详细分析表明，$m_{0}$、$m_{1/2}$、$A_{0}$、$\tan{\beta}$、$\delta^{LR}_{ct}$的最可能值预计分别为4.83 TeV、2.54 TeV、1.90 TeV、41.5 和6$\times10^{-2}$，使用平坦先验。如果使用自然先验，相应的值分别为3.25 TeV、2.13 TeV、1.90 TeV、44.7 和5.9$\times10^{-2}$。此外，将我们的模型与以味守恒的CMSSM作为基准模型进行比较，考虑到我们研究中使用的所有实验约束，得到的贝叶斯因子约为6。我们的分析还表明，最轻的中性微子质量约为1 TeV。 显示英文摘要

摘要： Flavour-violating couplings of Higgs boson with stop and scharm quarks could be very important as in addition to lifting the mass of the Higgs boson by a few GeV, it could also play a vital phenomenological role in reducing the Supersymmetry breaking scale significantly. In this work, we investigate effects of such flavour-violating couplings within the Constrained Minimal Supersymmetric Standard Model (CMSSM) framework in the context of LEP data, Higgs data at the LHC, precision observables and the relic density of the dark matter using Bayesian statistics. Our detailed analysis reveals that the most probable values of $m_{0}$, $m_{1/2}$, $A_{0}$, $\tan{\beta}$, $\delta^{LR}_{ct}$ are expected to be around 4.83 TeV, 2.54 TeV, 1.90 TeV, 41.5, and 6.1$\times10^{-2}$, respectively, with flat priors. The corresponding values translate into 3.25 TeV, 2.13 TeV, 1.90 TeV, 44.7, and 5.9$\times10^{-2}$, respectively, if the natural priors are used. Furthermore, a comparison of our model with the CMSSM of flavour-conservation as the base model yields a Bayes factor of about 6 while taking into account all the experimental constraints used in our study. Our analysis also reflects that the lightest neutralino would have a mass of about 1 TeV.
