Abstract

The Positron Annihilation to Dark Matter Experiment (PADME) uses the positron beam of the DA

\Phi

ΦNE Beam-Test Facility, at the Laboratori Nazionali di Frascati (LNF) to search for a Dark Photon A’. The search technique studies the missing mass spectrum of single-photon final states in

e^+e^-\rightarrow A'\gamma

e+e−→A′γ annihilation in a positron-on-thin-target experiment. This approach facilitates searches for new particles such as long lived Axion-Like-Parti-cles, protophobic X bosons and Dark Higgs. This talk illustrated the scientific program of the experiment and its first physics results. In particular, the measurement of the cross-section of the SM process

e^+e^-\rightarrow \gamma\gamma

e+e−→γγ at

\sqrt{s}

s=21 MeV was shown.
