The calorimeters of the PADME experiment

The PADME experiment is under construction at the Frascati National Laboratories of INFN to explore the coupling between ordinary and dark matter. This will be done through the detection of Standard Model photons produced in the reaction $e^{+}{e}^{-}\to \gamma A^{\prime }$. The measurement of the photons 4-momentum allows to reconstruct the missing mass spectrum of this process, where the $A^{\prime }$ could appear as a peak. To this purpose, two independent electromagnetic calorimeters are used. The layout of the two detectors, and their expected performance measured during prototypes tests, are here presented.
