| contents | We investigate both the $Z$ and $H$ poles solutions for the Higgsino mass parameter $μ>0$ and $μ<0$ for the neutralino dark matter in light of the LHC supersymmetry searches and the direct detection dark matter experiments, LUX-ZEPLIN (LZ), in the Generalized Minimal Supergravity (GmSUGRA). Our study indicates that the latest experimental constraints from the LHC and LZ Collaborations exclude the light Higgsinos in the $Z$ and $H$ pole regions for the $μ>0$ case. Interestingly, for the $μ< 0$ case, a very light Higgsinos can still be consistent with the current constraints from the electroweakino searches and LZ experiment in the $Z$ and $H$ poles. Consequently, the $μ< 0$ case appears more promising and thus requires the dedicated efforts to make definitive conclusions about their current status from the experimental Collaborations. In this framework, our findings indicate a deviation of up to $2σ$ from the central value of \( a_μ\equiv (g-2)_μ/2 \), resonating with the experimental results reported by CMD and BDM. |
