在micrOMEGAs内重新设定直接探测极限和对非标准暗物质方案的影响
Recasting direct detection limits within micrOMEGAs and implication for non-standard Dark Matter scenarios
摘要：
直接探测实验获得90%的上限上的弹性散射截面的暗物质与核子假设点的相互作用和标准的天体物理学和宇宙学参数。在本文中，我们提供了一个重铸的限制，从XENON 1 T，PICO-60，CRESST-III和DarkSide-50，并将它们包括在micrOMEGA。然后，该代码可以用来直接施加约束，从这些实验的通用暗物质模型在不同的假设下的DM速度分布或对核形状因子。此外，新的限制的弹性散射截面，可以在光的t-通道介质或毫荷电粒子的存在下获得。
英文摘要：
Direct detection experiments obtain 90% upper limits on the elastic scattering cross sections of dark matter with nucleons assuming point-like interactions and standard astrophysical and cosmological parameters. In this paper we provide a recasting of the limits from XENON1T, PICO-60, CRESST-III and DarkSide-50 and include them in micrOMEGAs. The code can then be used to directly impose constraints from these experiments on generic dark matter models under different assumptions about the DM velocity distribution or on the nucleus form factors. Moreover new limits on the elastic scattering cross sections can be obtained in the presence of a light t-channel mediator or of millicharged particles.
