关于粒子振荡

On particle oscillations

Marek Góźdź, Andrzej Góźdź

摘要:

中微子在传播过程中会改变它们的味道,这一点已经得到了坚定的证实。这一特征归因于这样的事实,即每个味本征态是三个质量本征态的叠加,它们以不同的频率传播。这种观点虽然被广泛接受,但在最简单的方法中是错误的,需要基于量子场论中的波包描述进行非常复杂的处理。在这次交流中,我们提出了一个新颖、简单得多的解释,并表明可以以自然的方式获得大质量粒子之间的振荡。我们使用量子力学的框架,时间是一个物理可观察的,而不仅仅是一个参数。

英文摘要:

It has been firmly established, that neutrinos change their flavour during propagation. This feature is attributed to the fact, that each flavour eigenstate is a superposition of three mass eigenstates, which propagate with different frequencies. This picture, although widely accepted, is wrong in the simplest approach and requires quite sophisticated treatment based on the wave-packet description within quantum field theory. In this communication we present a novel, much simpler explanation and show, that oscillations among massive particles can be obtained in a natural way. We use the framework of quantum mechanics with time being a physical observable, not just a parameter.
