Search for a Hypothetical 16.7 MeV Gauge Boson and Dark Photons in the NA64 Experiment at CERN

We report the first results on a direct search for a ncw 16.7 McV boson (X) which could explain the anomalous excess of e(+) e(-) pairs observed in the excited Be-8* nucleus decays. Because of its coupling to electrons, the X could be produced in the bre
