Hunting down the X17 boson at the CERN SPS

E. Depero, Yu. M. Andreev, D. Banerjee +53

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 obs…

Improved limits on a hypothetical X(16.7) boson and a dark photon decaying into $e^{+} e^{-}$ pairs

D. Banerjee, J. Bernhard, V. E. Burtsev +51

The improved results on a direct search for a new X(16.7 MeV) boson which could explain the anomalous excess of $e^{+} e^{-}$ pairs observed in the excited 8Be nucleus decays ("Berilliu…
