无菌中微子。一个简短的介绍

Sterile Neutrino. A short introduction

Dmitry V. Naumov

摘要:

这是一个教学介绍的主要概念的不育中微子-一个假设的粒子,创造解决一些异常的中微子数据和保持一致性与观察到的宽度的$W$和$Z$玻色子。我们简要回顾现有的异常和振荡参数,最好地描述这些数据。我们更详细地讨论了如何可以观察到无菌中微子,以及它可能存在的后果。特别是,我们注意到一个可能的损失的一致性与不育中微子的中微子振荡的模型,这种效果可能是一个重大的重要性,相对于3 $ν$模型。本文还简要地回顾了寻找不育中微子态的现状。

英文摘要:

This is a pedagogical introduction to the main concepts of the sterile neutrino - a hypothetical particle, coined to resolve some anomalies in neutrino data and retain consistency with observed widths of the $W$ and $Z$ bosons. We briefly review existing anomalies and the oscillation parameters that best describe these data. We discuss in more detail how sterile neutrino can be observed, as well as the consequences of its possible existence. In particular, we pay attention to a possible loss of coherence in a model of neutrino oscillations with sterile neutrinos, where this effect might be of a major importance with respect to the 3$ν$ model. The current status of searches for a sterile neutrino state is also briefly reviewed.
