论文摘要
在这项工作中，我们介绍了对向量暗物质（VDM）直接检测横截面的次要订单（NLO）校正的先前计算更新。所研究的模型是标准模型（SM）的最小扩展，其中一个额外的向量玻色子和一个额外的复杂标量场，其中矢量是DM候选者。我们已经计算了与旋转的横截面，用于用核子散射VDM粒子。现在，我们为直接检测DM粒子提供了NLO横截面的更新。我们进一步讨论了NLO校正对直接检测DM实验的灵敏度的现象学意义。
In this work we present an update to a previous calculation of the Next-to-Leading Order (NLO) corrections to the Vector Dark Matter (VDM) direct detection cross section. The model under investigation is a minimal extension of the Standard Model (SM) with one extra vector boson and one extra complex scalar field, where the vector is the DM candidate. We have computed the spin-independent cross section for the scattering of the VDM particle with a nucleon. We now provide an update to the NLO cross section for the direct detection of the DM particle. We further discuss the phenomenological implications of the NLO corrections for the sensitivity of the direct detection DM experiments.
