论文摘要
中微子经历了随机扰动,因为它们传播经验的反应,使中微子振荡在距离上受阻。如果重力是一种量子力,包括中微子和虚拟黑洞之间的相互作用,则这种扰动可能是由于时空本身的波动而引起的。在这项工作中,我们对启发式中微子 - 虚拟黑洞相互作用方案对中微子传播的影响进行了建模,并评估了天体物理和大气中微子中产生的信号。我们证明了如何在开放量子系统的框架中表示这些效果,从而使对此类系统的实验限制与量子重力效应有关。最后,我们考虑了这种普朗克量表物理学在当前中微子实验中观察到的能量的能量依赖性,并表明在某些情况下,对普朗克量表物理学的敏感性远低于“自然”期望。
Neutrinos undergoing stochastic perturbations as they propagate experience decoherence, damping neutrino oscillations over distance. Such perturbations may result from fluctuations in space-time itself if gravity is a quantum force, including interactions between neutrinos and virtual black holes. In this work we model the influence of heuristic neutrino-virtual black hole interaction scenarios on neutrino propagation and evaluate the resulting signals in astrophysical and atmospheric neutrinos. We demonstrate how these effects can be represented in the framework of open quantum systems, allowing experimental constraints on such systems to be connected to quantum gravitational effects. Finally, we consider the energy-dependence of such Planck scale physics at energies observed in current neutrino experiments, and show that sensitivity to Planck scale physics well below the `natural' expectation is achievable in certain scenarios.
