The PADME experiment at the Frascati National Laboratory of INFN has performed a
search for the hypothetical X17 particle, by observing the product of the collisions
of the positron beam from the DAΦNE LINAC on a diamond fixed target.
The beam energy has been varied in the range
265–300 MeV, corresponding to values of √s between 16.4 and 17.5 MeV,
completely covering the the CoM...
In the last years, the efforts towards finding subGeV new physics have increased. This Light Dark World is vast and unknown, however, we know that the components of different theories must live in that world. From the experimental side, there is also a great effort to disentangle and understand what could hide the Light Dark World. NA64 is a fixed target experiment at CERN SPS that search for...
