Seong Youl Choi, Jae Sik Lee, Jubin Park

摘要:

本文对标准模型及其三种典型扩展模型,即复单重态扩展模型(cxSM)、四种不含树能级Higgs介导的变味中性流(FCNC)的双Higgs-doublet模型(2 HDMs)和最小超对称扩展模型(MSSM)中的希格斯玻色子衰变进行了系统全面的回顾和分析。我们总结了SM希格斯玻色子和希格斯玻色子玻色子的衰变宽度的理论预测出现在其扩展考虑到所有可能的衰变模式。我们将他们的研究和分析CP偶,CP奇,CP混合中性希格斯玻色子玻色子和带电的衰变模式。本文重点介绍了在LHC上发现的质量约为125 GeV的中性Higgs玻色子的性质,并给出了对其进行精确分析所得到的约束条件,旨在通过对相关物理信息的相干整合,使之成为一个完备的、统一的、可用于研究SM及更远空间中希格斯玻色子玻色子衰变的物理模型。

英文摘要:

We make an updated review and a systematic and comprehensive analysis of the decays of Higgs bosons in the Standard Model (SM) and its three well-defined prototype extensions such as the complex singlet extension of the SM (cxSM), the four types of two Higgs-doublet models (2HDMs) without tree-level Higgs-mediated flavor-changing neutral current (FCNC) and the minimal supersymmetric extension of the SM (MSSM). We summarize the theoretical predictions for the decay widths of the SM Higgs boson and those of Higgs bosons appearing in its extensions taking account of all possible decay modes. We incorporate them to study and analyze decay patterns of CP-even, CP-odd, and CP-mixed neutral Higgs bosons and charged ones. We put special focus on the properties of a neutral Higgs boson with mass about 125 GeV discovered at the LHC and present constraints obtained from precision analysis of it. This review is intended to be self-contained and consolidated by coherently integrating relevant physics information for studying decays of Higgs bosons in the SM and beyond.
