Next-generation experiments like DUNE and Hyper-K must disentangle genuine CP violation from a possible impostor: non-standard neutrino interactions that mimic or mask the signal.
260 kilotons of water, 99,000 next-generation photomultipliers, and a 0.6 GeV neutrino beam from J-PARC. Hyper-K's role in the 2030s CP-violation discovery push.
The most ambitious neutrino experiment ever built. What DUNE will measure in the 2030s and what its definitive results should look like by 2040.
What CP violation in the neutrino sector would mean, why it matters for leptogenesis, and how T2K, NOvA, DUNE, and Hyper-K are hunting for it.
A single number — the CP-violating phase δ_CP — could be the reason that matter survived in the early universe. T2K and NOvA are measuring it. DUNE and Hyper-Kamiokande will pin it down.
From a beam line in Illinois to a 14,000-ton plastic detector in northern Minnesota, NOvA has been hunting for CP violation and pinning down the neutrino mass ordering since 2014.
Every few seconds, the J-PARC accelerator complex in Tokai produces a burst of muon neutrinos and points them at a giant water tank under a mountain near Toyama. The experiment is called T2K — and it has been quietly leading the CP-violation hunt for fifteen years.
DUNE uses a 1300 km baseline and a liquid-argon time-projection chamber; Hyper-K uses a 295 km baseline and a 260-kiloton water Cherenkov tank. Both will measure CP violation in neutrinos — but with complementary strengths and different systematic risks.
Everything you need to understand neutrino oscillation — from the original Pontecorvo proposal in 1957, through the experimental discoveries at Super-Kamiokande and SNO, to the open questions about CP violation and the mass ordering. The single most comprehensive reference on neutrinos changing flavor as they travel.
Eight times the size of Super-Kamiokande, Hyper-Kamiokande is being built into a mountain in Hida. When it starts in 2027, it will be the most sensitive neutrino detector ever assembled.
Construction is underway on the largest neutrino experiment ever built. Its mission: catch the asymmetry between matter and antimatter — by firing a beam through 1,300 kilometers of rock.
