论文摘要
Higgs玻色子与停止和Scharm Quarks的风味侵略耦合可能非常重要，因为除了将Higgs Boson的质量提高一些GEV外，它还可以显着减少超对称性断裂量表，从而发挥至关重要的现象学作用。在这项工作中，我们研究了在LEP数据的背景下，LHC上的HIGGS数据，精度可观察到的HIGGS数据，Precision可观察物以及使用贝叶斯统计的暗物质统计数据中的Precision可观察到的HIGGS数据，在LEP数据的背景下，HIGGS数据在受约束的最小超对称标准模型（CMSSM）框架中的影响。我们的详细分析表明，$ m_ {0} $，$ m_ {1/2} $，$ a_ {0} $，$ \tanβ$，$tanβ$，$δ^{lr} _ {ct} $的最可能值最可能的值预计，预计4.83 tev，2.54 tev，1.90 tev，41 $ 1.1.1.1.1.1.11.1 $ n.111.11.11.11.11.11 $ n.111.11.11 $ n-和6.11 $ n.111.11.11.11.11.11.11.11 $。分别具有平坦的先验。相应的值分别转化为3.25 TEV，2.13 TEV，1.90 TEV，44.7和5.9 $ \ times10^{ - 2} $，如果使用了自然先验。此外，在考虑到我们研究中使用的所有实验约束时，我们的模型与风味保存的CMSSM进行了比较。我们的分析还反映出，最轻的中性诺的质量约为1 TEV。
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 $m_{0}$, $m_{1/2}$, $A_{0}$, $\tanβ$, $δ^{LR}_{ct}$ 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.
