暗物质的直接探测:在简化模型框架中的精确预测

Direct detection of dark matter: Precision predictions in a simplified model framework

Christoph Borschensky, Gabriele Coniglio, Barbara Jäger, Josef Jochum, Vincent Schipperges

摘要:

本文在含有s和t通道介质的简化模型框架下,计算了暗物质粒子与核子散射的次领先阶QCD修正。这些结果是匹配的威尔逊系数和运营商的有效场论,通常用于演示实验结果的自旋无关和自旋相关的直接检测率。详细的唯象研究说明了对撞机搜索暗物质和直接探测实验CRESST和氙的互补范围。在树级贡献中的抵消效应的情况下,在组合s+ t通道模型的情况下,单回路校正可以对排除限制产生特别大的影响。

英文摘要:

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.
