    Abstract

    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+e- pair, producing a narrow resonance in the QED trident spectrum. Using APEX test run data, we searched in the mass range 175-250 MeV, found no evidence for an A →e+e- reaction, and set an upper limit of α/αA10-6. Our findings demonstrate that fixed-target searches can explore a new, wide, and important range of masses and couplings for sub-GeV forces.
