论文摘要
我们研究了真空中微子振荡如何受到量子场理论的因果，非线性和状态依赖性修饰的影响，该理论可以使用量子力学的许多世界公式来解释。这种效果是由Yukawa的Higgs-neutrino相互作用引起的，该相互作用会导致中微子质量特征状态之间的非线性干扰。这导致光，主动中微子的振荡模式发生了很小的变化，而不会改变振荡频率。在振荡消失的大基线上，非线性效应也被抑制，一旦与环境纠缠在一起，质量本征态之间也不会产生相关性。我们的示例提供了一种计算非线性量子力学和现场理论效应的方法，该理论可能会探讨许多世界的物理现实。
We study how vacuum neutrino oscillations can be affected by a causal, nonlinear and state-dependent modification of quantum field theory that may be interpreted using the many-worlds formulation of quantum mechanics. The effect is induced by a Higgs-neutrino Yukawa interaction that causes a nonlinear interference between the neutrino mass eigenstates. This leads to a tiny change in the oscillation pattern of light, active neutrinos without altering the oscillation frequencies. At large baselines where the oscillations disappear, the nonlinear effect is also suppressed and does not source correlations between the mass eigenstates once they are entangled with the environment. Our example provides a way to compute effects of nonlinear quantum mechanics and field theory that may probe the possible physical reality of many worlds.
