Search for a New Gauge Boson in Electron-Nucleus Fixed-Target Scattering by the APEX Experiment
We present a search at the Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling α′ to electrons. Such a particle A′ can be produced in electron-nucleus fixed-target scattering and then decay to an e[superscript +]e[superscript -] pair, producing a narrow resonance...
