Abstract We study supersymmetric (SUSY) models in which the muon g −2 discrepancy and the dark matter relic abundance are simultaneously explained. The muon g − 2 discrepancy, or a 3σ deviation between the experimental and theoretical results of the muon anomalous magnetic moment, can be resolved by SUSY models, which implies at least three SUSY multiplets have masses of O 100 $$ \mathcal{O}(100) $$ GeV. In particular, models with the bino, higgsino and slepton having O 100 $$ \mathcal{O}(100) $$ GeV masses are not only capable to explain the muon g−2discrepancybutnaturallycontainstheneutralinodarkmatterwiththeobservedrelic abundance. We study constraints and future prospects of such models; in particular, we find that the LHC search for events with two hadronic taus and missing transverse mo-mentum can probe this scenario through chargino/neutralino production. It is shown that almost all the parameter space of the scenario can be probed at the high-luminosity LHC, and a large part can also be tested at the XENON1T experiment as well as at the ILC.
