  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.
