We're going to need an independent experiment to see this "X17" before anyone truly believes it's a new particle. Some example major particle discoveries over the last few decades (and the independent experiments which observed them): Higgs (ATLAS & CMS at CERN); Top quark (CDF & D0 Fermilab); W & Z Bosons (UA1 and UA2 at CERN); J/Psi (Richter's team at SLAC & Ting's team at MIT). Some other fundamental particles were observed by a single experiment (the bottom quark, for example) and the community believed it, but in those cases it's always because a theory has already predicted the particle, and we've always been able to study them with future experiments anyway. So this won't gain traction unless another experiment can observe it.
