Neutrino oscillations at the wrong location?

Innovation News Network Feb. 9, 2024

Neutrino oscillations, discovered 25 years ago, break the Standard Model of particle physics and have been the subject of much investigation.To further study neutrino oscillation, Fermilab’s Short Baseline Neutrino (SBN) program has three detectors in the beam, placed at three very different distances to research if neutrinos are changing as a function of distance.

Can a theory ever die?

Symmetry feature

Neglected theories will wilt and wither but can bloom again with enough attention.

Three factoid cards, which look similar to playing cards or a baseball card, appear on a background of stars in a night sky (or in outer space) in a cartoon rendering. On each of the cards is a circle adjusted its sunglasses, presumably each a type of neutrino. Underneath these images on the cards are scribbles representing text and a question mark. In the upper left corner, the abbreviations for electron neutrino, a muon neutrino or a tau neutrino appear.

Which neutrino is the heaviest?

Symmetry feature

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 long-awaited results of the muon experiment will be announced soon

From China Science News, Yunnan.cn (China), April 1, 2021: The Muon g-2 experiment conducted at the Fermilab will soon announce the results after 20 years of waiting.
