This result isn't even peer-reviewed yet. All of this hype about the X17 particle is coming from a pre-print on the arXiv. https://arxiv.org/abs/1910.10459 They claim a 7.2 sigma result, but the distribution of the null-hypothesis (called PDF(exp) in the paper) was determined from simulations of one atomic transition and "external pair creation on the target backing", and the only source of systematic error they took…

Correct, and they are usually followed up by a published, peer-reviewed paper as well. I look forward to the day this one also gets reviewed and published.
Higgs boson discovery pre-print: https://arxiv.org/abs/1207.7214 Higgs boson discovery paper: https://www.sciencedirect.com/science/article/pii/S037026931...
It's essentially the same text.

Great
