中微子质量不为零的存在表明可能存在多个标准模型中性费米子。当这种状态足够重以至于它们不能在振荡中产生时，它们被称为重中性轻子（HNL）。在这篇白色论文中，我们讨论了目前的实验状况，包括对撞机，β衰变，加速器，以及天体物理和宇宙学的影响。我们讨论了继续寻找HNL的重要性，以及它对我们理解关键基本问题的潜在影响，此外，我们还概述了下一代未来实验或即将到来的加速器运行场景的未来前景。
The existence of nonzero neutrino masses points to the likely existence of multiple Standard Model neutral fermions. When such states are heavy enough that they cannot be produced in oscillations, they are referred to as heavy neutral leptons (HNLs). In this white paper, we discuss the present experimental status of HNLs including colliders, beta decay, accelerators, as well as astrophysical and cosmological impacts. We discuss the importance of continuing to search for HNLs, and its potential impact on our understanding of key fundamental questions, and additionally we outline the future prospects for next-generation future experiments or upcoming accelerator run scenarios.
