Description
I will present new results on the hypothesised X17 particle, interpreted as a light Z´-boson, based on data from Coherent Elastic neutrino Nucleus Scattering (CEvNS) experiments at reactors and spallation sources as well as IceCube data on non standard neutrino interactions (NSI). The X17 has been introduced to explain observations of nuclear transitions such as p Li7 -> Be8* -> Be8 e+e- made by the ATOMKI experiment which recently has also been supported by results from the PADME experiment. I will show how the CEvNS data are better described by including the X17 and how by including the NSI data a single best fit region of neutrino and nucleus couplings to the X17 are singled out.
