论文摘要
在此处定义为1 MeV至1 GEV之间的质量，在理论上和现象学上都是一种有趣的可能性，在DM搜索领域的当前进步之一。 MEV-GEV地区的实验缺乏，它通过伽马射线的间接检测受到了挑战。因此，我们查看来自积分望远镜的低能X射线数据，并将其与预测的DM通量进行比较。我们得出了与其他技术的现有技术竞争的界限。至关重要的是，我们包括在银河辐射场和CMB上的反向康普顿散射的贡献，这比以前对20 MeV高于20 MeV的DM质量的研究更强。
Light Dark Matter (DM), defined here as having a mass between 1 MeV and about 1 GeV, is an interesting possibility both theoretically and phenomenologically, at one of the frontiers of current progress in the field of DM searches. Its indirect detection via gamma-rays is challenged by the scarcity of experiments in the MeV-GeV region. We look therefore at lower-energy X-ray data from the Integral telescope, and compare them with the predicted DM flux. We derive bounds which are competitive with existing ones from other techniques. Crucially, we include the contribution from inverse Compton scattering on galactic radiation fields and the CMB, which leads to much stronger constraints than in previous studies for DM masses above 20 MeV.
