Title A new direct detection electron scattering experiment to search for the X17 particle
Abstract A new electron scattering experiment (E12-21-003) [1] to verify and understand the nature of hidden sector particles, with particular emphasis on the so-called X17 particle, has been approved at Jefferson Lab. The search for these particles is motivated by new hidden sector models introduced to account for a variety of experimental and observational puzzles: excess in e +e ? pairs observed in multiple nuclear transitions, the 4.2? disagreement between experiments and the standard model prediction for the muon anomalous magnetic moment, and the small-scale structure puzzle in cos?mological simulations. The aforementioned X17 particle has been hypothesized to account for the excess in e +e ? pairs observed from the 8Be M1, 4He M0, and, most recently, 12C E1 nuclear tran?sitions to their ground states observed by the ATOMKI group. This experiment will use a high resolution electromagnetic calorimeter to search for or set new limits on the production rate of the X17 and other h
