Search For A New Gauge Boson In Electron-Nucleus Fixed-Target Scattering By The Apex Experiment
PHYSICAL REVIEW LETTERS, no. 19 (2011)
关键词
摘要
We present a search at the Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling alpha' 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 s...更多
