title = "Search for production of an invisible dark photon from π0 decays at NA62",

abstract = "A search for an invisible dark photon A' has been performed, exploiting the efficient photon-veto capability and high resolution tracking of the NA62 detector at CERN. The signal stems from the chain K+ → π+π0 followed by π0 → A'γ. No significant statistical excess has been identified. Upper limits on the dark photon coupling to the ordinary photon as a function of the dark photon mass have been set, improving on the previous limits over the mass range 60–110 MeV/c2",
