Search for a new 17 MeV resonance via e+e− annihilation with the PADME Experiment
/ Spadaro, Tommaso (speaker) (INFN e Laboratori Nazionali di Frascati (IT))
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 CoM region identified by the ATOMKI collaboration as significant for observing the postulated X17 particle.The result of the analysis shows an about 2-sigma excess corresponding to the mass indicated by the ATOMKI experiment. A new data taking campaign, with an improved detector is planned to start in the summer of 2025, with the aim of pushing forward the sensitivity of the search.
Refreshments will be served at 10:30

Geometrical Methods of Effective Field Theories (HEFT workshop)
/ Manohar, Aneesh Vasant (speaker) (Univ. of California San Diego (US))
I discuss recent progress in using geometrical methods to compute radiative corrections in quantum field theories, and give some applications to SMEFT and ChPT. I will also briefly discuss infinite anomalous dimensions in EFTs..

Superconducting nanowire detectors: from quantum science to high-energy physics
/ Korzh, Boris Alexander (speaker) (Universite de Geneve (CH))
Superconducting nanowire detector development was driven largely by quantum science during the last decade, but emerging high-energy physics applications are motivating a new wave of breakthroughs. They are capable of detecting photons (X-ray to far-infrared), low energy electrons, ions and neutral molecules and most recently have been tested for relativistic particle detection [...]
