摘要:
宏观暗物质(或称 macro)提供了一大类可替代粒子暗物质的候选体。这些候选体将主要通过弹性散射转移能量,而如果一个 macro 穿过大气层,这种线性能量沉积将产生可观测信号。我们研究 macro 穿过大气层时产生的荧光发射。我们估算 EUSO-SPB2 在约束二维参数空间($σ$ 对 $M$)方面的灵敏度,其中 $M$ 是 macro 的质量,$σ$ 是其横截面积。
英文摘要:
Macroscopic dark matter (or macro) provides a broad class of alternative candidates to particle dark matter. These candidates would transfer energy primarily through elastic scattering, and this linear energy deposition would produce observable signals if a macro were to traverse the atmosphere. We study the fluorescence emission produced by a macro passing through the atmosphere. We estimate the sensitivity of EUSO-SPB2 to constrain the two-dimensional parameter space ($σ$ vs. $M$), where $M$ is the macro mass and $σ$ its cross sectional area.
