论文摘要
在当前的粒子对撞机实验中，高自旋颗粒的可观察信号很少。同时，对暗物质颗粒的旋转没有明显的限制。因此，自然要考虑高自旋颗粒作为暗物质的可能性。在这项工作中，我们通过DM电子散射分别研究了（旋转$ 3/2 $）Gravitino暗物质（旋转$ 3/2 $）暗物质和（Spin- $ 2 $）大型暗物质。都考虑了DM的自旋非依赖性（SI）和自旋非依赖性（SD）相互作用。使用Xenon10，Xenon100和Xenon1t的实验数据，我们可以给出DM质量和横截面之间的限制关系。为了简化，我们仅在领先顺序上计算CORSS部分，而仅关注（伪）标量介质。此外，通过评估和分析DM的形式，我们发现，如果调解器是标量，则没有明显的信号可以以旋转$ 3/2,2 $与旋转$ 0,1/2,1 $的旋转$ 3/2,2 $区分DM。
The observable signal of higher-spin particles is rare in current particle collider experiments. In the meantime, there have no evident constraints on the spin of the dark matter particles. And thereby it is natural to consider the possibility that the higher-spin particles behaves as dark matter. In this work, we investigate the direct detection of (spin-$3/2$) gravitino dark matter and (spin-$2$) massive KK-graviton dark matter respectively through the DM-electron scattering. Both the spin-independent (SI) and spin-independent (SD) interactions of DM are considered. Using the experiment datas of XENON10, XENON100 and XENON1T, we could give the restriction relation between the DM mass and cross section. For simplification, we only compute the corss section at leading order, while merely focus on the (pseudo)scalar mediators. Moreover, by evaluating and analyzing the form factor of DM, we uncover that if the mediator is scalar there have no significant signals to distinguish the DM with spin $3/2,2$ from the one with spin $0,1/2,1$.
