中子衰变异常的暗物质解释

Dark Matter Interpretation of the Neutron Decay Anomaly

Bartosz Fornal, Benjamin Grinstein

摘要:

在束流实验和瓶实验中测量的中子寿命之间存在着长期的差异。我们建议用中子的暗衰变通道来解释这种异常,其中涉及一个或多个处于终态的暗扇区粒子。如果这些粒子中的任何一个是稳定的,它们就可能是暗物质。我们构建代表性的粒子物理模型符合所有实验约束。

英文摘要:

There is a long-standing discrepancy between the neutron lifetime measured in beam and bottle experiments. We propose to explain this anomaly by a dark decay channel for the neutron, involving one or more dark sector particles in the final state. If any of these particles are stable, they can be the dark matter. We construct representative particle physics models consistent with all experimental constraints.
