Description

NA64 is a fixed target experiment at the CERN SPS aiming at a sensitive search for hidden sectors. The A′, called dark photon, could be generated in the reaction e−Z→e−ZA′ of 100 GeV electrons dumped against an active target which is followed by the prompt invisible decay A′→χχ. The experimental signature of this process would be a clean event with an isolated electron and large missing energy in the detector. Results on the search for the visible A' -> e+e− decays, as well as X→ e+e− decay of a new 17 MeV X boson, which could explain a recently observed anomaly in the 8Be transitions will be also discussed.
