Randall-Sundrum模型中引力介导的暗物质湮灭

Gravity-Mediated Dark Matter Annihilation in the Randall-Sundrum Model

Thomas D. Rueter, Thomas G. Rizzo, JoAnne L. Hewett

摘要:

暗物质的观测证据源于它的引力相互作用,到目前为止还没有证据表明暗物质通过其他方式相互作用。我们研究的模型中,暗物质的相互作用是纯粹的引力在兰德尔Sundrum的背景。特别是,从扭曲的第五维产生的卡鲁扎-克莱因塔引力子可以提供可行的湮灭通道到标准模型的最终状态,我们发现,我们可以实现的湮灭截面,$\left< σv \right>$,这是与自旋1暗物质的情况下观察到的遗迹丰度一致的值。我们研究这些模型采用当前的光子线和连续间接暗物质搜索的约束,并评估狩猎的信号,这些模型在未来的直接和间接探测实验的前景。

英文摘要:

Observational evidence for dark matter stems from its gravitational interactions, and as of yet there has been no evidence for dark matter interacting via other means. We examine models where dark matter interactions are purely gravitational in a Randall-Sundrum background. In particular, the Kaluza-Klein tower of gravitons which result from the warped fifth dimension can provide viable annihilation channels into Standard Model final states, and we find that we can achieve values of the annihilation cross section, $\left< σv \right>$, which are consistent with the observed relic abundance in the case of spin-1 dark matter. We examine constraints on these models employing both the current photon line and continuum indirect dark matter searches, and assess the prospects of hunting for the signals of such models in future direct and indirect detection experiments.
