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.

    A new U(1) extension of the Standard Model is proposed, with a neutrino-coupled gauge boson and a dark Higgs scalar as a freeze-in dark matter candidate, yielding an estimated coupling between 10^-8.5 and 10^-6 times ...

    A projection study showing that HL-LHC tau-pair data could determine the CP mixing angle of a hypothetical 95 GeV resonance to within roughly 0.27 to 0.47 radians at 90% confidence.
