Abstract

Abstract: We show that dark photons (A^′) with masses ∼ 10-80 MeV can be probed in the decay μ+→e+νeν¯μA′, A^′ → e⁺e⁻, with the upcoming Mu3e experiment at the Paul Scherrer Institute (PSI) in Switzerland. With an expected 10¹⁵ (5.5 × 10¹⁶) muon decays in 2015–2016 (2018 and beyond), Mu3e has the exciting opportunity to probe a substantial fraction of currently unexplored dark photon parameter space, probing kinetic-mixing parameter, ϵ, as low as ϵ² ∼ 10⁻⁷ (10⁻⁸). No modifications of the existing Mu3e setup are required.
