Search for production of an invisible dark photon from π0 decays at NA62
A search for an invisible dark photon A%27 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%2b → π%2bπ0 followed by π0 → A%27γ. 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 © 2019 CERN for the benefit of the ATLAS and CMS Collaborations.
