description Recent data from the ATOMKI group continue to confirm their claim of the existence of a new <math display="inline"><mo>∼</mo><mn>17</mn><mtext> </mtext><mtext> </mtext><mi>MeV</mi></math> particle. We review and numerically analyze the data and then put into context constraints from other experiments, notably neutrino scattering experiments, such as the latest reactor antineutrino coherent elastic neutrino nucleus scattering data and unitarity constraints from solar neutrino observations. We show that minimal scenarios are disfavored and discuss the model requirements to evade these constraints.
