We investigate the prospects for detecting light leptophilic dark sectors with a missing-momentum experiment at NA64 running in muon mode. In particular, we consider models in which dark matter connects to the visible sector through a lepton- or muon-specific scalar mediator. These scalars can also account for the ∼3.5σ discrepancy between the measured and predicted values of (g−2)μ . We emphasize the complementarity between NA64-μ and other terrestrial and astrophysical probes.
