“That’s a 20 years old anomaly in neutrino physics which has been above the discovery threshold since 2018, but chances are you’ve never even heard of it.”
The muon g-2 result got headlines everywhere without reaching discovery significance. MiniBooNE confirmed the LSND neutrino anomaly at 6 sigma and almost nobody covered it. Physics press follows the press releases, not the statistics. The result that cleared the bar is the one you never heard about.
