轴子和引力子是最轻的超对称粒子（LSP）和宇宙中冷暗物质的有力候选者。假设带电轻子是第二轻的超对称粒子（NLSP），我们展示了如何使用NLSP衰变来探测强子轴子模型中的轴子LSP场景以及大型强子对撞机和国际直线对撞机中的引力LSP场景。我们展示了如何通过实验来识别自然界中实现的场景。就轴基 LSP 而言，NLSP 衰减将允许人们估计轴基质量和 Peccei-Quinn 尺度的值。
The axino and the gravitino are well-motivated candidates for the lightest supersymmetric particle (LSP) and also for cold dark matter in the Universe. Assuming that a charged slepton is the next-to-lightest supersymmetric particle (NLSP), we show how the NLSP decays can be used to probe the axino LSP scenario in hadronic axion models as well as the gravitino LSP scenario at the Large Hadron Collider and the International Linear Collider. We show how one can identify experimentally the scenario realized in nature. In the case of the axino LSP, the NLSP decays will allow one to estimate the value of the axino mass and the Peccei–Quinn scale.
