Article: Particle Physics Models for the \(17\MeV\) Anomaly in Beryllium Nuclear DecaysRecently there’s some press (see links below) regarding early hints of a new particle observed in a nuclear physics experiment. In this bite, we’ll summarize the result that has raised the eyebrows of some physicists, and the hackles of others.
