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.
Neutrinos are neutral, meaning the magnets in a particle accelerator can’t manipulate them. So how can scientists make a dense beam of neutrinos for their experiments? Neutrino physicist Kirsty Duffy and Fermilab accelerator operator Laura Bolt explain the power of protons and how teams can generate intense beams of neutrinos using particle accelerators.
Researchers from more than 50 countries collaborate with Fermilab to develop state-of-the-art technologies and solve the mysteries of matter, energy, space and time. Take a look at 10 ways Fermilab and its partners advanced science and technology in 2021.
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.
Neutrinos are weird. Scientists didn’t expect them to change type as they travel, but they do! So how do we study this weird phenomenon of neutrino oscillation? On this episode, neutrino physicist Kirsty Duffy and special guest Anne Norrick will explore how to build a long-distance neutrino experiment.
Figuring out which type of neutrino is heaviest, or solving the puzzle of neutrino mass hierarchy, would be a huge leap in our understanding of both neutrinos and the physics that govern our universe. The NoVA experiment or DUNE could help physicists do just that.
The Fermilab particle accelerator complex set a record beam power earlier this year, thanks to the high-quality work of numerous teams and individuals. The successful completion of the NuMI 2020 shutdown work prepared the target facility for this achievement.
The NOvA experiment, best known for its measurements of neutrino oscillations using particle beams from Fermilab accelerators, has been turning its attention to measurements of cosmic phenomena. In a series of results, NOvA reports on neutrinos from supernovae, gravitational-wave events from black hole mergers, muons from cosmic rays, and its search for the elusive monopole.
From Sci News, Oct. 2, 2020: A research team from four national laboratories, including Fermilab and Argonne, have undertaken work at two Fermilab neutrino experiments — MiniBooNE and NOvA — to construct a model of how neutrinos interact with atomic nuclei. This knowledge is essential to unravel an even bigger mystery: why during their journey through space or matter neutrinos magically morph from one into another of three possible types or flavors.
