Seminario di Fenomenologia delle Particelle Elementari INFN/DIFI – Dr. Enrico Nardi (INFN Laboratori Nazionali di Frascati)

Certain anomalies observed in the angular correlation spectra of
electron/positron pairs produced in nuclear transitions of 8Be, 4He
and 12C can be interpreted as the emission of a bosonic particle with
a mass of 17 MeV, that promptly decays into e+e−. I review the current
status of these anomalies, and some theoretical interpretation for the
hypothetical new particle. I will also describe the prospects for
validating or disproving the X17 hypothesis by means of a particle
physics experiment.
