论文摘要
我们介绍了在具有S-和T渠道介质的简化模型框架内将暗物质颗粒散射从核子中散射出核子的近级QCD校正的计算。这些结果与有效场理论的威尔逊系数和运算符相匹配，该系数通常用于呈现旋转非依赖性和旋转依赖性直接检测率的实验结果。详细的现象学研究说明了对撞机搜索暗物质和直接检测实验CRESST和XENON的互补范围。在树级贡献中取消效应的情况下，在组合S+T通道模型的情况下，单循环校正对排除限制可能会产生特别大的影响。
We present a calculation of the next-to-leading order QCD corrections for the scattering of Dark Matter particles off nucleons in the framework of simplified models with s- and t-channel mediators. These results are matched to the Wilson coefficients and operators of an effective field theory that is generally used for the presentation of experimental results on spin-independent and spin-dependent direct detection rates. Detailed phenomenological studies illustrate the complementary reach of collider searches for Dark Matter and the direct detection experiments CRESST and XENON. In the case of cancellation effects in the tree-level contributions, one-loop corrections can have a particularly large impact on exclusion limits in the case of combined s+t-channel models.
