The furore around Fermilab’s latest findings is typified by this BBC link – https://www.bbc.com/news/science-environment-66407099 … Pallab Ghosh reported on a recent finding at Fermilab in the US. They may be getting nearer to discovering the existence of a fifth force in nature. What have they found? Evidence, it is declared, of subatomic particles, muons, that are not behaving in the way predicted by the current theory of sub atomic physics. Is an unknown force acting on the muons?

At https://www.nature.com/articles/d41586-023-02532-6 … for the press release from the journal Nature – which the BBC report is  based upon. Magnetisim in muons, like electrons, is strong. A muon, it seems, is a heavier type of electron. Muons have an electric charge. They also spin on themselves. They act like tiny bar magnets, we are told. It seems the new results, aided by modeling, do not require adjustment to the mainstream theory. Interesting to note – muons are similar to electrons but 207 times more massive. They are unstable as they are created in particle collisions. They also decay back into electrons, shortly afterwards. One may wonder if the fifth force is electricity itself.
