Abstract
The recently published result from the Fermilab “MUON G-2” experiment has confirmed the
persistent 3-4 $\sigma$ discrepancy between the experimental result from BNL for the anomalous
magnetic moment of the muon, $(g−2)_\mu$ , and its Standard Model (SM) prediction. The combination
of the two measurements yields a deviation of 4.2 $\sigma$ from the SM value. Here, we review the
parameter space of the electroweak (EW) sector of the Minimal Supersymmetric Standard Model
(MSSM), that can accommodate the anomaly while being in full agreement with other experimental
data, particularly the direct searches for EW particles at the LHC and dark matter (DM) relic density
and direct detection constraints. We find that the combined constraints set an upper limit of
~ 600 GeV for the LSP and NLSP masses establishing clear targets for the future collider searches.
