“…PADME is hosted at the Beam Test Facility of LNF [3,4]. It looks for a DP produced via the reaction e + + e − → γ + A using positrons accelerated to 550 MeV by the laboratory's LINAC, impinging on the electrons of a 100 µm thick active diamond target, able to measure beam position and intensity [5].…”

Facility searches for dark photons produced in the annihilation of positrons with the electrons of a fixed target. The strategy is to look for the reaction e + + e − → γ + A , where A is the dark photon, which cannot be observed directly or via its decay products. The electromagnetic calorimeter plays a key role in the experiment by measuring the energy and position of the final-state γ. The missing four-momentum carried away by the A can be evaluated from this information and the particle mass inferred. This paper presents the design, construction, and calibration of the PADME's electromagnetic calorimeter. The results achieved in terms of equalisation, detection efficiency and energy resolution during the first phase of the experiment demonstrate the effectiveness of the various tools used to improve the calorimeter performance with respect to earlier prototypes.

“…The main aim of the Positron Annihilation into Dark Matter Experiment (PADME), hosted at the Laboratori Nazionali di Frascati, is the search for an invisibly decaying DP. Placed in the laboratories Beam Test Facility [9], it exploits the LINAC to accelerate positrons that then annihilate with electrons coming from a target, to look for the reaction:…”

“…An upgraded pulsing system has been recently commissioned, allowing to deliver beam pulses of increasing length, up to 5 µs, so that, after having optimized the RF power and phases and the magnetic focusing in the LINAC, electron or positron beams could get accelerated close Patras 2017 to the maximum energy, with a width of several hundreds of ns. An upgrade of the DAΦNE LINAC energy up to 1 GeV has been also proposed [3]. This will extend the parameter space to lower values of and increase the A' mass range to M A' < 32 MeV.…”

“…The PADME experiment [1], hosted in the DAΦNE [2] Beam-Test Facility (BTF) [3] at Laboratori Nazionali di Frascati (LNF) of INFN, is designed to search for the dark photon by using an intense positron beam hitting a light target. The A' can be observed by searching for an anomalous peak in the spectrum of the missing mass measured in events with a single photon in the final state.…”

Massive photon-like particles are predicted in many extensions of the Standard Model with a hidden sector where dark matter is secluded. They are vector bosons mediating the interaction between dark matter particles and can be produced in scattering of ordinary particles through a faint mixing to the photon. Most of the present experimental constraints on this "dark photon" (A') rely on the hypothesis of dominant decays to lepton pairs. The PADME experiment will search for the e + e − → γA' process in a positron-ontarget experiment, assuming a decay of the A' into invisible particles of the hidden sector. The positron beam of the DAΦNE Beam-Test Facility, at Laboratori Nazionali di Frascati of INFN, will be used. A fine-grained, high-resolution calorimeter will measure the momentum of the photon in events with no other activity in the detector, thus allowing to measure the A' mass as the missing mass in the final state. In about one year of data taking, a sensitivity on the interaction strength (ε 2 parameter) down to 10 −6 is achievable in the mass region M A' < 23.7 MeV. The experiment is currently under construction and it is planned to take data in 2018. The status of PADME and its physics potential will be reviewed.
