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 \( \mathcal{O}(100) \) GeV. In particular, models with the bino, higgsino and slepton having \( \mathcal{O}(100) \) 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.
