Abstract—

The physics of neutrino oscillations is a rapidly developing area of study of the fundamental properties of these particles. In this article, we present the status of an experimental study of three-flavor oscillations after the largest conference in neutrino physics (Neutrino 2020). Prospects and unresolved problems are discussed.

Notes

  1. The preprint was published in arxiv in September 2010, the article was published in March 2011.

  2. Fit values including Super-Kamiokande data are given.

  3. Thus, their use for testing unitarity is not entirely correct. Nevertheless, the authors of [85] argue that in the absence of unitarity in the experimental data, fitting them in the unitarity approximation will generate a certain structure from different types of experiments on complex planes, which can be considered as an indication of nonunitarity.
