SUMMARY:A light Z’ as a solution of the 17 MeV anomaly
DESCRIPTION:Motivated by an anomaly observed in the decay of an excited state of Beryllium by the Atomki collaboration\, we study an extension for the Standard Model with a gauged U(1)’ symmetry. We show that this scenario complies with a variety of experimental results and is able to explain the potential presence of a resonant spin-1 gauge boson\, Z’\, with a mass of 17 MeV in the Atomki experimental data\, for appropriate choices of U(1)’ charges and Yukawa interactions.
