Description
The PADME experiment at the Frascati National Laboratory of INFN has performed a search for the hypothetical X17 particle, by observing the product of the collisions of the positron beam from the DAΦNE LINAC on a diamond fixed target.
The beam energy has been varied in the range 265–300 MeV, corresponding to values of √s between 16.4 and 17.5 MeV, completely covering the center of mass region identified by the ATOMKI collaboration as significant for observing the postulated X17 particle. In my talk I will present the result of the analysis of these data, and briefly discuss the physics potential of the forthcoming PADME run, with an improved detector.
