Researchers in US and Japan offer insight into ghostly neutrinos

Summary:

– NOvA and T2K experiments combine nearly a decade of observations.

– Study measures mass gap between two neutrino types with <2% uncertainty.

– Research may help explain why the universe is mostly matter, not antimatter.

WASHINGTON — Neutrinos are tiny particles that can pass through everything, rarely interacting with matter. They are the universe’s most abundant particles, and trillions of them zip through our bodies every second without us noticing. Yet scientists are still struggling to underst and them.

A new study that combines results from two major neutrino experiments in Japan and the United States is now offer ing some of the best information to date about these ghostly particles.
