Particle theorist are currently working on many Dark Matter scenarios beyond the simple WIMP model, motivated by the absence of robust evidence for Dark Matter from current dedicated experiments. We plan to propagate these new Dark Matter scenarios to cosmology, and to test their signature on high precision cosmological data, beyond the minimal framework of perfectly stable, decoupled and cold particles. We will derive new bounds on the dark matter annihilation cross-section, decay rate, scattering cross-section with other species, self-interaction rate and velocity dispersion. These bounds will be based on new CMB anisotropy data, new Large Scale Structure data, and also on the cross-correlation of these observations with the Fermi gamma-ray map.

粒子理论家目前正在研究许多超出简单WIMP模型的暗物质场景，这是由于目前专门实验中缺乏暗物质的有力证据。我们计划将这些新的暗物质场景传播到宇宙学中，并在高精度的宇宙学数据上测试它们的签名，超越完美稳定，解耦和冷粒子的最小框架。我们将推导出暗物质湮灭截面，衰变率，与其他物种的散射截面，自相互作用率和速度色散的新的界限。这些界限将基于新的CMB各向异性数据，新的大尺度结构数据，以及这些观测与费米伽马射线图的互相关。
