Neutrinos

Physicists at the University of Massachusetts Amherst propose that a record-breaking neutrino detected in 2023 originated from the explosion of a primordial black hole carrying a 'dark charge.' The particle's energy, 100,000 times greater than that produced by the Large Hadron Collider, puzzled scientists since only the KM3NeT experiment recorded it. Their model, published in Physical Review Letters, could also hint at the nature of dark matter.

Scientists at Fermilab's MicroBooNE experiment have determined that the long-hypothesized sterile neutrino does not exist, based on high-precision measurements of neutrino behavior. The findings, published in Nature, show neutrinos acting as expected without evidence of a fourth type, closing a decades-old theory. This result paves the way for new investigations and advanced experiments like DUNE.
