NOvA Experiment

Neutrinos are among the most abundant particles in the universe, a billion times more so than those composing stars.

Exciting news! After two years, NOvA is taking neutrino data from the NuMI beamline again! Here is a beautiful event from the first few days of our run. We are incredibly grateful to everyone who has worked hard to make this happen!

@uw_icecube On, Wisconsin!

[NOvA Experiment @novaexperiment]

Huge congratulations to Prof. Francis Halzen on being named the 2026 Nobel Prize laureate for physics.

[NOvA Experiment @novaexperiment]

@uw_icecube is a fantastic experiment that has produced extraordinary results over the last 16 years, and we're excited to see what comes next. An excellent reminder that neutrinos are an amazing probe of the Universe!

Fermilab has an article out on our new spokesperson, Linda Cremonesi! https://t.co/GkEhIa9Gxr

No signal was observed in the analyzed dataset. With the detector’s large surface area and minimal overburden, we achieve the strongest limits reported to date in several regions of monopole speed and mass.

Today in PRD we have a publication describing the first ionization-based search for magnetic monopoles in NOvA using more than seven years of data collected with the Far Detector. See the publication here: https://t.co/QmvGyYHPAK

[NOvA Experiment @novaexperiment]

To identify such rare signatures in the presence of nearly 150 kHz of cosmic-ray background, the Far Detector employs a data-driven monopole trigger that continuously searches for these characteristic event patterns within the cosmic flux.

That's a wrap on #neutrino2026! We had a blast in California, see you at the next Neutrino in two years!

[NOvA Experiment @novaexperiment]

The posters cover a lot of our physics - three-flavour oscillation analyses, searches for new physics program, our work on exotic phenomena, neutrino interaction measurements, and our test beam.

📸: A lot of NOvA Collaborators!

NOvA collaborators presented a huge number of posters at #neutrino2026 at University of California, Irvine this week.

@OhioState @OhioStateNews and by combining our results with those presented by JUNO yesterday, we prefer the normal ordering of neutrinos with a Bayes factor of 15.74 (Normal ordering is 16x more likely) or a significance of 1.88 sigma.

This morning, Zoya Vallari (@OhioState @OhioStateNews) presented NOvA's latest results to a packed room at #neutrino2026. See the slides here: https://t.co/pvJOvpEVaY 📸 Georgia Nissen, Adam Lister

[NOvA Experiment @novaexperiment]

@OhioState @OhioStateNews We have new deep dives on our three-flavour oscillation results, new world-leading limits on sterile neutrinos, ...

[Mario AAO. @mario_aao]

Awesome, new interactive resources from @novaexperiment for you to learn mote about #Neutrinos.
🔮🎊🔮

[NOvA Experiment @novaexperiment]

This new manusrcipt shows what the combination of NOvA's 10 year dataset and the anticipated high-precision JUNO measurement might tell us for many possible measured values and precisions.

[NOvA Experiment @novaexperiment]

Interested to know what NOvA and JUNO might be able to say about the neutrino mass ordering when JUNO releases results? You can look into our crystal ball 🔮 at this website, https://t.co/vhDPyEoL5x, with a longer write up in our preprint here: https://t.co/mLesbuiumQ

In the correct ordering, these measurements should agree well, while in the incorrect ordering they would disagree.
