The topic of this workshop is the “X17” particle, which existence has been claimed in a series of recent experiments. In the workshop, the current status of the new experimental research and the new advances of the theoretical studies about this hypothetical particle will be presented and discussed.

The issue is of great interest, for the great impact on the study of the beyond standard model physics and fundamental symmetries. It would be the first confirmation of a “dark matter” particle, and the possible mediator of a fifth force. At present many theoreticians and experimental groups are studying this issue; the gathering of a number of them could have many positive outcomes, first of all to elucidate the matter, and to trigger new ideas and projects.
