NOvA

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.

From the Universities Research Association: Michael Dolce, a physics doctoral candidate at Tufts University, was awarded a stipend as part of the URA’s Fall 2020 Visiting Scholars Program to compare data collected between NOvA’s Near and Far detector. While on the VSP grant, Dolce worked alongside his sponsor Dr. Louise Suter, a NOvA expert and Fermilab scientist who provided him a direct line to the laboratory and valuable guidance.

The NOvA collaboration has released the result of its latest measurement of neutrino oscillations. The results provide greater insight into neutrino properties, specifically mass ordering and charge parity symmetry.
