论文摘要
中微子是我们最不了解的标准模型（SM）粒子，通常是由于它们与其他SM颗粒的相互作用较弱。除此之外，关于中微子之间的相互作用，即他们的自我互动知之甚少。 SM预测中微子的自我互动的水平超出了任何当前的实验能力，从而为超越SM相互作用的可能性提供了许多能量尺度的可能性。在这份白皮书中，我们回顾了当前对中微子自我互动的了解，从宇宙学到天体物理学再到实验室的各种探针。我们还讨论了这种自我互动的理论动机，包括中微子群众和与暗物质的可能联系。展望未来，我们讨论了下一代及以后的搜索功能，突出了未来发现这种超越SM物理学的可能性。
Neutrinos are the Standard Model (SM) particles which we understand the least, often due to how weakly they interact with the other SM particles. Beyond this, very little is known about interactions among the neutrinos, i.e., their self-interactions. The SM predicts neutrino self-interactions at a level beyond any current experimental capabilities, leaving open the possibility for beyond-the-SM interactions across many energy scales. In this white paper, we review the current knowledge of neutrino self-interactions from a vast array of probes, from cosmology, to astrophysics, to the laboratory. We also discuss theoretical motivations for such self-interactions, including neutrino masses and possible connections to dark matter. Looking forward, we discuss the capabilities of searches in the next generation and beyond, highlighting the possibility of future discovery of this beyond-the-SM physics.
