中微子振荡的再解释

Reinterpreting Neutrino Oscillations

M. Bergevin

摘要:

这封信为观测到的中微子振荡现象提出了另一种量子力学图像。假设中微子通过非绝热(或局域)相互作用与新的粒子场相互作用,这改变了它们的味道。此外,假设每个中微子味态只能有一个关联质量,从而使它们成为自然界的基本粒子。与物质相互作用相关的有效质量取代了中微子混合角的概念。初步证据表明,左手中微子和右手反中微子振荡不同,这意味着电荷宇称破坏。鉴于在某些中微子振荡实验中观察到的明显异常现象,人们猜测存在第四个(无菌)中微子,因此有必要研究其他机制预测的振荡行为,以确定它们是否能更自然地解释现有的数据。

英文摘要:

This letter proposes an alternative quantum mechanical picture for the observed phenomena of neutrino oscillations. It is assumed in the following that neutrinos interact via diabatic (or localised) interactions with a new particle field, which changes their flavor. Furthermore, it is assumed that each neutrino flavor state can only have a single associated mass thereby making them fundamental particles of nature. The effective masses associated with matter interactions replace the concept of neutrino mixing angles. Preliminary evidence that left-handed neutrinos and right-handed antineutrinos oscillate differently is presented, implying charge-parity violation. Given the apparent anomalous observations of some neutrino oscillation experiments, which have led to speculations about the existence of a fourth (sterile) neutrino, it is worth examining the oscillation behavior predicted by alternative mechanisms to determine if they more naturally explain the available data.
