I will discuss the recent experimental results from the ATOMKI group which measured the spectrum ofinternal pair conversion e+e- events in the decay of an excited state of beryllium-8 to its ground state.  They observe a resonant-like structure in the invariant mass of the e+e- which is suggestiveof a new boson at 17 MeV.  I’ll review the experimental results and the types of theories whichcan describe them.
