Too many anti-neutrinos: Evidence builds for new anomaly

Bump ahead.

Tl;dr: A third experiment has reported an unexplained bump in the spectrum of reactor-produced anti-neutrinos. Speculations for the cause of the signal so far focus on incomplete nuclear fission models.

Neutrinos are the least understood of the known elementary particles, and they just presented physicists with a new puzzle. While monitoring the neutrino flux from nearby nuclear
