Description
The high-intensity setup, trigger system flexibility, and detector performance – high-frequency tracking of beam particles, redundant PID, ultra-high-efficiency photon vetoes – make NA62 particularly suitable for searching for new-physics effects from different scenarios. We report the results of a search for π0 decays to one photon and an invisible massive dark photon. From a total of about 400$ million π0 decays, no signal is observed beyond the expected fluctuation of the background and limits are set in the plane of the dark photon coupling to ordinary photon versus dark photon mass.
