中微子振荡与测不准关系

Neutrino oscillations and uncertainty relations

S. M. Bilenky, F. von Feilitzsch, W. Potzel

摘要:

我们表明,相干味中微子态的产生(和检测)由于动量坐标海森堡不确定性关系。Mandelstam-Tamm时间-能量不确定性关系需要非定态中微子状态才能发生振荡,并决定了振荡所需的时间间隔(传播长度)。我们比较了不同的中微子振荡方法,这些方法基于不同的物理假设,但在标准中微子振荡实验中得到了相同的中微子跃迁几率表达式。我们表明,穆斯堡尔中微子实验可以允许区分不同的方法,我们提出的论点,有利于163 Ho-163 Dy系统这样的实验。

英文摘要:

We show that coherent flavor neutrino states are produced (and detected) due to the momentum-coordinate Heisenberg uncertainty relation. The Mandelstam-Tamm time-energy uncertainty relation requires non-stationary neutrino states for oscillations to happen and determines the time interval (propagation length) which is necessary for that. We compare different approaches to neutrino oscillations which are based on different physical assumptions but lead to the same expression for the neutrino transition probability in standard neutrino oscillation experiments. We show that a Moessbauer neutrino experiment could allow to distinguish different approaches and we present arguments in favor of the 163Ho-163Dy system for such an experiment.
