neutrinos

Laura Munteanu, Mathieu Perrin-Terrin and Stephen Dolan describe how neutrino tagging, proposed in 1979 and demonstrated at CERN, promises to tame the systematics limiting the next generation of neutrino-oscillation experiments. The post Neutrinos on the clock appeared first on CERN Courier .

Neutrinos are very difficult to detect. And when they are detected, pinpointing their sources is likewise difficult. New research shows that the most energetic neutrino ever detected must have had an extraordinarly energetic source. It could even be primordial.

There's a less than 5 percent chance that earlier anomalies can be explained by fourth neutrino "flavor."

A deep-sea detector glimpsed a particle with 220 million billion electron volts of energy — around 20 times as energetic as any neutrino seen before.
