In search of new particles with PADME

Full text: Not available
Several contemporary particle physics experiments at accelerators aim to contribute in the quest to
describe the properties of the Dark matter by looking for new particles. One of them is the Positron
Annihilation into Dark Matter Experiment (PADME), at the Laboratori Nazionali di Frascati of
INFN. Its main goal is to search for a Dark Photon (A’) by studying the annihilation of beam
positrons on a fixed target. Since 2018, two data taking periods were completed successfully,
collecting O($10^{13}$) positrons on target. In 2022 the detector setup was then modified to explore the
existence of the so-called "X17" particle, postulated to explain an anomalous effect observed by
the ATOMKI collaboration. In this paper the PADME experiment is presented, the main results
and the possible future prospects are discussed.
