“…The LHC constraints are more efficient in excluding the Smuon co-annihilating mechanism than the electroweakino co-annihilating mechanism. The reason is that the Smuon corresponds to the NLSP for the former mechanism, and it can increase the leptonic signal rate since heavy sparticles will decay into the Smuon [69,92]. It was verified that the signal regions for more than 3 leptons of CMS-SUS-16-039 and for more than 200 GeV of E miss T of CMS-SUS-20-001 played a crucial role in excluding the samples.…”

“…1 are lighter, they will be more copiously produced at the LHC to increase the events containing multiple leptons. In Appendix A of [92], the reason why µ 500 GeV is disfavored was also explained by analytic expressions. Since lighter sparticles are forbidden, tan β has to be larger than about 20 to solve the discrepancy.…”

“…Thus the predictions for a SUSY µ in the NMSSM is almost the same as that in the MSSM. Even so, the two theories may still display different features in fitting experimental constraints due to their possibly distinct DM physics and sparticle signals at the LHC [69,92].…”

It is well known that excessively heavy supersymmetric particles (sparticles) are disfavored to explain the (g − 2) µ anomaly, but few people realize that moderately light sparticles are also disfavored by the LHC probes of supersymmetry. We take the Next-to-Minimal Supersymmetric Standard Model as an example to illustrate the latter point. It is found that, if the theory is required to explain the anomaly at 2σ level and meanwhile keep consistent with the LHC results, the following lower bounds may be set: tan β 20, |M 1 | 275 GeV, M 2 300 GeV, µ 460 GeV, m μL 310 GeV, and m μR 350 GeV, where M 1 and M 2 denote gaugino masses, µ represents the Higgsino mass, and m μL and m μR are the mass of Smuons with L and R denoting their dominant chiral component. This observation has significant impacts on dark matter (DM) physics, e.g., the popular Zand Higgs-funnel regions have been excluded, and the Bino-dominated neutralino DM has to co-annihilate with the Wino-dominated electroweakinos (in most cases) and/or Smuons (in few cases) to obtain the correct density. It is also inferred that these conclusions should apply to the Minimal Supersymmetric Standard Model since the underlying physics for the bounds are the same.

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 Z 3 -symmetry, predicting more stable vacuum states than the Z 3 -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.
