The gallium deficit is measured relative to a calculated capture rate. A September 2026 paper offers a possible nuclear explanation, with important fitted inputs. MicroBooNE and KATRIN constrain sterile-neutrino interpretations,…
The matter excess is measured; its origin is unresolved. Leptogenesis links that problem to hypothetical heavy neutrinos. A 2026 calculation shows why a particle with almost no role in light-neutrino…
Neutrinos are identified through rare interactions that leave light, charge or nuclear-recoil signals. Compare the detection methods, then see what COHERENT’s new journal result adds to the established picture of…
KM3NeT inferred an energy of about 220 PeV for a neutrino recorded in 2023. IceCube’s September 2026 follow-up found no supporting emission from its direction. The event’s energy remains uncertain,…
Francis Halzen’s Nobel Prize highlights a new way to study cosmic accelerators. IceCube detects their elusive neutrinos, but a detector signal is only the first step. Identifying a source requires…
A hundred trillion neutrinos pass through your body every second and never touch you, and for most of the twentieth century physicists were sure they weighed nothing at all. They…
In 59 days of running, JUNO caught 2,379 antineutrinos and pinned down two oscillation parameters 1.6 times more precisely than every previous experiment combined. It was not built for either…
The commissioning paper reports 1785 photoelectrons per MeV, 20.6 m scintillator transparency and uranium below 10⁻¹⁶ g/g. The first physics paper reports the world's best solar oscillation parameters from 59.1…
Some cosmological fits push the total neutrino mass towards or below the minimum required by oscillations. KATRIN measures a different effective mass. Understanding the tension means keeping the datasets, confidence…
