Description
The decays of neutral Higgs bosons into Standard Model fermions and gauge-bosons in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) are investigated at the full one-loop order with some higher-order QCD corrections. We take mixing effects for the external Higgs particles consistently into account. In the beginning, some formal aspects of our approach are discussed, before we compare our results to the predictions of existing public tools. Especially the decays of heavy Higgs-doublet states into gauge bosons are dominated by higher-order corrections; popular tree-level approximations fail. Finally, our framework is employed to investigate the properties of a light singlet-dominated state with a mass close to 95 GeV. We find scenarios which can interpret the fluctuations reported by LEP in the bb searches, and by CMS in the diphoton searches as true signals.
