量子失配:中微子振荡中“量子性”的一种强有力度量

Quantum mismatch: a powerful measure of "quantumness" in neutrino oscillations

Dibya S. Chattopadhyay, Amol Dighe

AI总结:

提出“量子失配”作为中微子振荡量子性的度量,在两味极限下提取干涉项,并在三味场景中提供修正定义,适用于物质效应可忽略的长基线和反应堆中微子实验。

摘要:

中微子振荡的量子本质将体现在有和没有中间观测的中微子存活概率之间的失配中。我们提出这种“量子失配”作为中微子振荡中量子性的度量,它在两味极限下精确提取干涉项。在完整的三味场景中,我们提供了 Leggett-Garg 和量子失配度量的修正定义。这些适用于测量中微子存活概率且物质效应可忽略的长基线和反应堆中微子实验。

英文摘要:

The quantum nature of neutrino oscillations would be reflected in the mismatch between the neutrino survival probabilities with and without an intermediate observation. We propose this ``quantum mismatch'' as a measure of quantumness in neutrino oscillations, which precisely extracts the interference term in the two-flavor limit. In the full three-flavor scenario, we provide modified definitions of the Leggett-Garg and quantum mismatch measures. These are applicable for long-baseline and reactor neutrino experiments that measure neutrino survival probabilities with negligible matter effects.
