摘要：

In this work we present the computation of the Higgs boson decay into a photon and a Z(0) boson at the one-loop level in the framework of the next-to-minimal supersymmetric standard model (NMSSM). The numerical evaluation of this decay width was performed within the framework of the SLOOPS code, originally developed for the minimal supersymmetric standard model but which was recently extended to deal with the NMSSM. Thanks to the high level of automation of SLOOPS, all contributions from the various sector of the NMSSM are consistently taken into account, in particular the nondiagonal chargino and sfermion contributions. We then explored the NMSSM parameter space, using HIGGSBOUNDS and HIGGSSIGNALS, to investigate to what extent these signal can be enhanced.
