Search for Invisible Decays of Sub-GeV Dark Photons in Missing-Energy Events at the CERN SPS

We report on a direct search for sub-GeV dark photons (A'), which might be produced in the reaction e(-)Z -> e(-)ZA' via kinetic mixing with photons by 100 GeV electrons incident on an active target in the NA64 experiment at the CERN SPS. The dark photon
