sterile neutrino

From CERN Courier, March 8, 2019: Newly published results from the MINOS+ experiment at Fermilab cast fresh doubts on the existence of the sterile neutrino — a hypothetical fourth neutrino flavor that would constitute physics beyond the Standard Model. MINOS+ studies how muon neutrinos oscillate into other neutrino flavors as a function of distance travelled.

From New Scientist, Nov. 21, 2018: Elusive though it is, the sterile neutrino would be a real boon. It could make sense of experimental anomalies stretching back decades, and give us the first confirmed glimpse of physics beyond what we know. Subscription required.

From Cosmos, Nov. 28, 2018: MiniBooNE researchers have published a paper in the journal Physical Review Letters, reporting a possible trace of a fourth neutrino, an addition to the three of the Standard Model.

From Scientific American, July 5, 2018: This editorial weighs in on the latest result from the MiniBooNE experiment. The author says that, while winning experiments may soon give us clarity, at this time there is no resolution to the sterile neutrino question.

From CNN, June 19, 2018: Fermilab scientist Don Lincoln explains how studying neutrinos became an intellectual industry. There were dozens of independent experiments telling a consistent story, each reporting similar values for the parameters being studied. Well, except for one.
