NOvA

The NOvA experiment published some of the most precise neutrino oscillation measurements to date including the difference in mass between neutrinos of different flavors with a precision of 1.5%

Throughout this year, Fermilab’s dedicated scientists, engineers, technicians and operations staff came together to drive discoveries, advance American innovation and prepare the lab for a bright future.

For more than two decades, a particle beam from Fermilab has been aimed at the NOvA experiment in Arrowhead, Minn. where researchers have been trying to understand neutrinos.

New data from the NOvA experiment at Fermilab in the US contain no evidence for so-called “sterile” neutrinos, in line with results from most – though not all – other neutrino detectors to date.

The NOvA collaboration scientists recently published a study finding no evidence of sterile neutrinos, but their work puts the tightest constraints on parameter space to date for where sterile neutrinos could be found.

The NOvA collaboration presented findings at the Neutrino conference in Milan in June 2024 with results that are likely to be evidence of a new phenomenon. With twice the data, the team of NOvA physicists are comparing muon neutrino and antineutrino oscillations to determine the mass hierarchy.

The Innovation Platform investigates how the NOvA experiment at Fermilab is working to determine the role of mysterious neutrinos. To find out more about the NOvA experiment’s goals and recent progress, Innovation Platform recently spoke to NOvA co-spokespersons Patricia Vahle, Professor of Physics at William & Mary, and scientist Alex Himmel from Fermilab.

As part of the international NOvA collaboration, William & Mary scientists are one step closer to unraveling the mysteries of neutrinos, with new results recently presented at the Neutrino 2024 conference. The latest results from the collaboration move science toward larger discoveries about the “ghost” particles of the universe.

The international collaboration presented their first results with new data in four years, featuring a new low-energy sample of electron neutrinos and a dataset doubled in size.

From Phys.org, August 3, 2022: Fermilab’s NOvA experiment reports analysis on oscillation data delivering some of the most accurate estimates to date describing neutrino oscillations and providing important hints on two important aspects of neutrino physics—the ordering of neutrino masses and the degree of charge-parity (CP) violation. These results set the stage for the next generation of “long-baseline” experiments, like Hyper-K and DUNE, which will dramatically boost our ability to probe elusive aspects of neutrino physics.
