DESCRIPTION:The anomaly recently observed by the ATOMKI collaboration in t
 he angular correlations of electron–positron pairs emitted in nuclear tr
 ansitions of 8Be\, 4He and 12C has attracted significant attention in the 
 particle physics community. This effect can be interpreted as the emission
  of a bosonic particle with a mass of 17 MeV\, commonly referred to as the
  X17 particle. If confirmed\, such a particle would constitute clear evide
 nce of physics beyond the Standard Model. After an introduction to the ATO
 MKI anomaly\, including a summary of the experimental observations and the
 oretical interpretations\, this seminar will cover the current status of t
 he X17 searches at particle accelerators\, highlighting results from sever
 al experiments\, including MEG\, PADME and NA64\, emphasizing the compleme
 ntary experimental strategies employed in this search. I will then focus o
 n the NA64 experiment\, which uses high-intensity electron and muon beams 
 to search for feebly interacting particles at CERN SPS. Existing NA64 resu
 lts in the X17 search will be discussed\, followed by prospects for possib
 le future measurements\, aimed at providing a decisive test of the X17 exp
 lanation of the ATOMKI anomaly.\n\nhttps://indico.ific.uv.es/event/8386/
