NOvA

From Quanta Magazine, April 15, 2020: The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather than nothing. Fermilab scientist Debbie Harris comments on the T2K experiment’s latest result. Fermilab’s NOvA experiment and the international Deep Underground Neutrino Experiment, hosted by Fermilab, will also help provide a more precise understanding of the asymmetry.

From Science, April 15, 2020: Neutrinos behave differently from their antimatter counterparts, antineutrinos, report physicists on the T2K experiment. The result is far from conclusive, but the asymmetry, known as CP violation, could help explain how the newborn universe generated more matter than antimatter. NOvA spokesperson Patricia Vahle of William & Mary comments on the T2K result and NOvA’s measurements of CP violation. When the international Deep Underground Neutrino Experiment, hosted by Fermilab, comes online, it will be able to make more precise measurements of neutrinos’ behavior.

New results from the T2K experiment in Japan rule out with 99.7% confidence nearly half of the possible range of values that could indicate how neutrinos behave compared to their antimatter counterparts.

From Forbes, Dec. 6, 2019: Fermilab scientist Don Lincoln gives a primer on neutrinos, neutrino oscillation and how studying neutrinos can help scientists explain the observed dominance of matter in the universe. And they’re doing just that with two Fermilab experiments, NOvA and DUNE.

The Cavalier Daily, Nov. 20, 2019: University physicists are beginning to make their mark on two multimillion dollar experiments in particle physics by contributing their research analyses to experiments at Fermilab for short: the Mu2e muon experiment and the NOvA neutrino experiment. NOvA is under way, and Mu2e is scheduled to begin in 2023.

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 Independent, July 27, 2019: A high school student spends his summer working on neutrinos and Fermilab’s NOvA neutrino experiment.

From NPR’s Here & Now, March 19, 2019: Fermilab is a global center for research into a tiny particle that could help answer some of the biggest questions in physics: the neutrino. Neutrinos have no electrical charge and almost no mass, but they’re everywhere. Fermilab Director Nigel Lockyer and Fermilab Deputy Chief Research Officer Bonnie Fleming talk about the Deep Underground Neutrino Experiment, visit the NOvA experiment and discuss the benefits of fundamental research.

From University of Missouri – Kansas City’s University News, Feb. 6, 2019: Sánchez, a scientist at Iowa State University, is a part of Fermilab’s NOvA neutrino experiment and the Deep Underground Neutrino Experiment. She also co-leads the ANNIE experiment at Fermilab.

From This Week in Science, Nov. 28, 2018: Fermilab scientist Alex Himmel talks about neutrinos, DUNE and the excitement of particle physics. Segment starts at 5:01.
