Bounds for invisible vector ρ meson decay were derived, analyzed, and compared with the current limits on searching dark matter in the accelerator based experiments. We demonstrate that the new approach can be effective tool to probe sub-GeV dark matter parameter space.enDark MatterMuonStandard ModelArtículoCC BY 4.0 ATTRIBUTION 4.0 INTERNATIONAL10.1103/PhysRevD.108.115005
