We discuss the experimental reach of the Frascati PADME experiment in searching for new light bosons via their resonant production in positron annihilation on fixed target atomic electrons. A scan in the mass range around 17 MeV will thoroughly probe the particle physics interpretation of the anomaly observed by the ATOMKI nuclear physics experiment. In particular, for the case of a spin-1 boson, the viable parameter space can be fully covered in a few months of data taking.

Combined Evidence for the $X_{17}$ Boson After PADME Results on Resonant Production in Positron Annihilation
The authors combine PADME positron annihilation data with nuclear transition results to report a refined mass for the hypothetical X17 boson of 16.88 ± 0.05 MeV.
