暗物质粒子的湮灭或衰变会产生单色伽马射线线，并造成弥散伽马射线背景。给出了从7GeV到200GeV的伽马射线谱线和从4.8GeV到264GeV的漫射伽马射线背景的通量上限，这些背景是由两年来在大部分天空上积累的费米大面积望远镜数据获得的。我们给出了产生伽马射线或对漫射光谱有贡献的暗物质模型的截面上限和衰变寿命下限，包括提出的解释帕米拉和费米宇宙线数据的模型。
Dark matter particle annihilation or decay can produce monochromatic gamma-ray lines and contribute to the diffuse gamma-ray background. Flux upper limits are presented for gamma-ray spectral lines from 7 to 200 GeV and for the diffuse gamma-ray background from 4.8 GeV to 264 GeV obtained from two years of Fermi Large Area Telescope data integrated over most of the sky. We give cross section upper limits and decay lifetime lower limits for dark matter models that produce gamma-ray lines or contribute to the diffuse spectrum, including models proposed as explanations of the PAMELA and Fermi cosmic-ray data.
