The aim of this project is a more precise calculation of the cross sections for the scattering of supersymmetric dark matter off Standard Model particles. It would allow for a more precise determination of the rates, with which dark matter can be detected directly on earth with scattering experiments like Xenon, and after its discovery of the supersymmetric model realised in Nature. Alternatively, new, even more sensitive experiments could be planned more reliably on the basis of these calculations. As the cross sections influence also the accretion of dark matter from the galactic halo in the earth or in the sun, these computations also contribute to more precise predictions of the rates for the indirect detection of dark matter via cosmic rays.

该项目的目的是对超对称暗物质在标准模型颗粒中散射的横截面的更精确计算。它可以更精确地确定速率，通过Xenon等散射实验，可以直接在地球上检测到暗物质，并在发现自然界中实现的超对称模型后。另外，根据这些计算，可以更可靠地计划新的，更敏感的实验。由于横截面也会影响地球中银河系子或太阳中银河系的暗物质增值，因此这些计算还有助于更精确地预测通过宇宙射线间接检测暗物质的速率的预测。
