摘　　要：It is well known that the observed Higgs mass is more naturally explained in the next-to-minimal supersymmetric standard model(NMSSM)than in the minimal supersymmetric standard model.Without any violation of this success,there are variants of the NMSSM that can lead to new phenomenologies.In this study,we propose a new variant of the NMSSM by imposing an unbroken R symmetry.We first identify the minimal structure of such a scenario from the perspective of both simplicity and viability,then compare the model predictions to current experimental limits,and finally highlight the main features that differ from those of well-known scenarios.
