论文摘要
我们研究了在随机重力波背景（SGWB）的影响下中微子风味振荡的修饰，在这种情况下，通过额外的Chern-Simons（CS）项来改变一般相对论。假设暗物质晕是轴的形式，则CS耦合将地球中微子风味振荡的模式修改为在某些频率范围内的总抑制。同时，光环中的SGWB可以在狭窄的频率范围内刺激轴突衰减到Gravitons中，从而导致在增强的SGWB菌株中潜在可检测到的共振峰。一致的图像将需要这些特征在超新星，重力波检测器和旨在以银河系光环中寻找轴的实验中的中微子检测中出现。
We investigate the modifications in the neutrino flavor oscillations under the influence of a stochastic gravitational wave background (SGWB), in a scenario in which General Relativity is modified by an additional Chern-Simons (CS) term. Assuming that the dark matter halo is in the form of axions, the CS coupling modifies the pattern of the neutrino flavor oscillations at Earth up to a total suppression in some frequency range. At the same time, the SGWB in the halo could stimulate the axion decay into gravitons over a narrow frequency range, leading to a potentially detectable resonance peak in the enhanced SGWB strain. A consistent picture would require these features to potentially show up in neutrino detection from supernovae, gravitational wave detectors, and experiments aimed at the search for axions in the Milky Way halo.
