Hunting down the X17 boson at the CERN SPS

Mostrar otras versiones (1)

Recently, the ATOMKI experiment has reported new evidence for the excess of $e^+e^-$ events with a mass $\sim $17 MeV in the nuclear transitions of $^4$He, that they previously observed in measurements with $^8$Be. These observations could be explained by the existence of a new vector $X17$ boson. S...
