This new experiment tells you that &quot;modern nuclear forces, including those derived within chiral effective field theory&quot; break down and cannot be used to describe what they observed. Here is the arxiv: https://arxiv.org/abs/2112.10582 It just tells you that their effective theory is no longer effective in these circumstances. Unless you actually observe something contradicts QED+QCD calculations, nothing fundamental is wrong. I can&#x27;t believe they pick such a clickbaity title for a serious publication and…</p><p><a href="https://hackerpaper.kaipfister.de/p/2112.10582/">Paper and discussion history</a>.
