论文摘要
在与125 GEV Higgs玻色子的SM信号强度的超对称性偏差中，由于SUSY在带有循环的图表中可能贡献了可能的贡献，这会导致有或没有循环图的过程的信号强度的不同偏差。在近乎最小的超对称标准模型（NMSSM）中，可能会发生其他偏差，因为与其他类似辛格的希格斯玻色子和/或其他衰变混合在一起，成对的光颗粒，例如中性中性粒子，伪量表，伪量表式希格斯·希格（Pseudo-Scalar Higgs Higgs Higgs Bosons或Singlet-Singlet-singlet-like higgs higgs higgs higgs bosons bosons bosons bosons bosons bosons of。在本文中，我们详细研究了这些“真正的” NMSSM偏差，不仅检查了它们可能的大小，而且还要寻找与其他通道有关的相关性或反相关性，以期希望在SUSY贡献中找到特定模式，而SUSY贡献主要发生在包括图中的循环中的过程中。整个NMSSM参数空间以确定性的方式进行采样。附录中详细讨论了新颖的扫描方法。我们发现了三个不同的区域，具有“真正的” NMSSM偏差，它们在很大程度上与生产模式无关。令人惊讶的是：一些区域表现出具有费米子和玻色子的最终状态之间的负相关性，这意味着如果费米子的信号强度降低了玻色子最终状态的信号强度增加，而其他区域则显示正相关。相关性的迹象是观察到的125 GEV Higgs Boson和Higgs Singlet之间质量差异的强大功能，因此寻找相关性可以给出有关Singlet Higgs Boson的存在和质量的有用暗示。这些“真正的” NMSSM效应的特征已在三个区域中的三个区域中的每个区域中都在代表性的基准点中进行了研究。这些基准点已在附录中详细介绍。
In Supersymmetry deviations from the SM signal strengths of the 125 GeV Higgs boson can occur, because of possible SUSY contributions in diagrams with loops, which leads to different deviations in signal strengths for processes with and without loop diagrams. In the Next-to Minimal Supersymmetric Standard Model (NMSSM) additional deviations may occur, because of the mixing with the additional singlet-like Higgs boson and/or additional decays into pairs of light particles, like neutralinos, pseudo-scalar Higgs bosons or singlet-like Higgs bosons. In this paper we study these "genuine" NMSSM deviations in detail to check not only their possible size, but also look for correlations or anti-correlations with respect to other channels in the hope to find specific patterns in the deviations as for the SUSY contributions, which occur predominantly in processes including loops in the diagrams. The whole NMSSM parameter space is sampled in a deterministic way. The novel scanning method is discussed in detail in the Appendix. We found three different regions with "genuine" NMSSM deviations, which are largely independent of the production mode. What was surprising: some regions show negativ correlations between final states with fermions and bosons meaning if the signal strengths for fermions decrease the signal strengths for bosonic final states increase, while other regions show positive correlations. The sign of the correlations is a strong function of the mass difference between the observed 125 GeV Higgs boson and the Higgs singlet, so looking for correlations could give useful hints about the existence and mass of the singlet Higgs boson. The features of these "genuine" NMSSM effects have been investigated in representative benchmark points for each of the three regions where a single effect is dominant. These benchmark points have been detailed in the Appendix.
