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.
Scientists working on the MINERvA experiment at Fermilab have examined a few ways neutrons can affect the measurements of antineutrino interactions.
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.
Fermilab’s MINERvA experiment gives a boost to the particle physics field by sharpening a model of a frequent, pesky phenomenon.
The physics community got a jolt last year when results showed for the first time that neutrinos and their antimatter counterparts, antineutrinos, might be the odd man out in the particle world and have different masses.
