The Next-to-Minimal Supersymmetric Standard Model (NMSSM) offers a richframework embedding physics beyond the Standard Model as well as consistentinterpretations of the results about the Higgs signal detected at the LHC. Weinvestigate the decays of neutral Higgs states into Standard Model (SM)fermions and gauge bosons. We perform full one-loop calculations of the decaywidths and include leading higher-order QCD corrections. We first discuss thetechnical aspects of our approach, before confronting our predictions to thoseof existing public tools, performing a numerical analysis and discussing theremaining theoretical uncertainties. In particular, we find that the decaywidths of doublet-dominated heavy Higgs bosons into electroweak gauge bosonsare dominated by the radiative corrections, so that the tree-levelapproximations that are often employed in phenomenological analyses fail.Finally, we focus on the phenomenological properties of a mostly singlet-likestate with a mass below the one at $125\,$GeV, a scenario that appears commonlywithin the NMSSM. In fact, the possible existence of a singlet-dominated statein the mass range around or just below $100\,$GeV would have interestingphenomenological implications. Such a scenario could provide an interpretationfor both the $2.3\sigma$ local excess observed at LEP in the $e^+e^-\to Z(H\tob\bar{b})$ searches at $\sim 98\,$GeV and for the local excess in the diphotonsearches recently reported by CMS in this mass range, while at the same time itwould reduce the "Little Hierarchy" problem.
