Status of the singlino-dominated dark matter in general Next-to-Minimal Supersymmetric Standard Model

Abstract

With the rapid progress of dark matter direct detection experiments, the attractiveness of the popular bino-dominated dark matter in economical supersymmetric theories is fading. As an alternative, the singlino-dominated dark matter in general Next-to-Minimal Supersymmetric Standard Model (NMSSM) is paying due attention. This scenario has the following distinct characteristics: free from the tadpole problem and the domain-wall problem of the NMSSM with a Z3-symmetry, predicting more stable vacuum states than the Z3-NMSSM, capable of forming an economical secluded dark matter sector to yield the dark matter experimental results naturally, and readily weaken the restrictions from the LHC search for SUSY. Consequently, it can explain the muon g-2 anomaly in broad parameter space that agrees with various experimental results while simultaneously breaking the electroweak symmetry naturally. In this study, we show in detail how the scenario coincides with the experiments, such as the SUSY search at the LHC, the dark matter search by the LZ experiment, and the improved measurement of the muon g-2. We provide a simple and clear picture of the physics inherent in the general NMSSM.

Study on muon MDM and lepton EDM in BLMSSM via the mass insertion approximation

“…The authors [29] study the muon g-2 in several GUT-scale constrained SUSY models, such as CMSSM/mSUGRA, pMSSM, CMSSM/mSUGRA extensions and GMSB/ AMSB extensions. The numerical result of muon g-2 is researched with the MultiNest technique for the parameter space [30][31][32] in the GNMSSM with a singlino-dominated neutralino as a dark matter candidate. The muon g-2 is further studied under  3 -NMSSM with LHC analyses in [33].…”
