| Abstract: | Searches are performed for both promptlike and long-lived dark photons, A ′ , produced in proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for A ′ → μ + μ − decays using a data sample corresponding to an integrated luminosity of 5.5 fb − 1 collected with the LHCb detector. Neither search finds evidence for a signal, and 90% confidence-level exclusion limits are placed on the γ – A ′ kinetic mixing strength. The promptlike A ′ search explores the mass region from near the dimuon threshold up to 70 GeV and places the most stringent constraints to date on dark photons with 214 < m ( A ′ ) ≲ 740 MeV and 10.6 < m ( A ′ ) ≲ 30 GeV . The search for long-lived A ′ → μ + μ − decays places world-leading constraints on low-mass dark photons with lifetimes O ( 1 ) ps . |
