This is a feeble attempt to try to catch a still elusive particle in a trancy way...

The X17 particle is a hypothetical subatomic particle proposed by Attila Krasznahorkay as the cause of anomalous measurement results near 17 MeV. The X17 particle could be the force carrier for a hypothetical fifth force, possibly connected with dark matter, and has been described as a 'protophobic (ie, "ignoring protons") X boson' with a mass of 17 MeV. The particle has been proposed to explain anomalous angles consistently observed in the decay of beryllium-8 atoms since 2015, and observed once in stable helium atoms in November 2019.
