Fermilab’s NOvA neutrino experiment records in its giant particle detector the passage of slippery particles called neutrinos and their antimatter counterparts, antineutrinos. Famously elusive, these particles’ interactions are challenging to capture, requiring the steady accumulation of interaction data to be able to pin down their characteristics. With five years’ worth of data, NOvA is adding to scientists’ understanding of neutrinos’ mass and oscillation behavior.
From The News Recorder, June 6, 2018: Scientists on Fermilab’s NOvA experiment — the world’s largest-baseline neutrino experiment — have detected strong evidence of muon antineutrinos oscillating into electron antineutrinos. Such phenomenon has never been observed before.
