论文摘要
对于一类宏观暗物质模型,核对暗物质的非弹性散射可以产生具有GEV尺度能量的电磁特征。具有公里尺寸的IceCube检测器是直接检测这种非弹性散射的理想选择。基于深核检测器的慢粒子触发因素,我们执行详细的信号和背景模拟,以估计发现电位。对于每次相互作用中的1 GEV沉积能量,我们发现IceCube可以探测深色物质质量最多一克。
For a class of macroscopic dark matter models, inelastic scattering of dark matter off a nucleus can generate electromagnetic signatures with GeV-scale energy. The IceCube detector, with its kilometer-scale size, is ideal for directly detecting such inelastic scattering. Based on the slow particle trigger for the DeepCore detector, we perform a detailed signal and background simulation to estimate the discovery potential. For order 1 GeV deposited energy in each interaction, we find that IceCube can probe the dark matter masses up to one gram.
