关注MeV缺口:低质量暗物质的间接探测

Minding the MeV Gap: the Indirect Detection of Low Mass Dark Matter

Kimberly K. Boddy, Jason Kumar

摘要:

我们认为间接探测低质量暗物质的前景占主导地位的夸克夫妇。如果质心能量低于280兆电子伏,运动学上允许的最终状态将由光子和中性π介子主导,在伽马射线望远镜上产生惊人的信号。事实上,已经提出了一系列新仪器,这将大大提高对这一能量范围内光子的灵敏度。我们发现,计划中的仪器可以提高目前的灵敏度,这种类型的暗物质模型高达几个数量级。

英文摘要:

We consider the prospects for the indirect detection of low mass dark matter which couples dominantly to quarks. If the center of mass energy is below about 280 MeV, the kinematically allowed final states will be dominated by photons and neutral pions, producing striking signatures at gamma ray telescopes. In fact, an array of new instruments have been proposed, which would greatly improve sensitivity to photons in this energy range. We find that planned instruments can improve on current sensitivity to dark matter models of this type by up to a few orders of magnitude.
