A bstract The recent confirmation by the Fermilab-based Muon g-2 experiment of ( g − 2) μ anomaly has important implications for allowed particle spectra in softly broken supersymmetry (SUSY) models with neutralino dark matter (DM). Generally, DM to be quite light, mass up a few hundred GeV, and bino-dominated if it is provide most Universe. Otherwise, higgsino or wino dominated also but only as strongly subdominant component at percent total density. These general patterns can easily found...
