Search for Dark Sector Physics in Missing Energy Events in the NA64 Experiment
A search is performed for a new sub-GeV vector boson (A′) mediated production of Dark Matter (χ) in the fixed-target experiment, NA64, at the CERN SPS. 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...
