论文摘要
在本文中，我们考虑循环校正底部夸克风味标型暗物质模型中无自旋wimp-nucleon散射横截面。我们专注于两种情况：（a）具有标量粒子作为中介的复杂标量暗物质； （b）带有矢量玻色子作为调解人的真实标量暗物质。在这两种情况下，直接检测横截面在树级处都是自旋依赖性或运动学上的。 WIMP-GLUON有效操作员，标量WIMP-QUARK有效运算符和Twist-2有效操作员引起的校正。数值结果表明，在两种情况下，环路诱导的旋转无链条散射横截面相当可观。
In this paper we consider loop corrections to the spin-independent WIMP-nucleon scattering cross section in bottom-quark flavored scalar-type dark matter models. We focus on two scenarios: (a) a complex scalar dark matter with a scalar particle as the mediator; and (b) a real scalar dark matter with a vector boson as the mediator. In both scenarios, the direct detection cross sections are either spin-dependent or kinematically forbidden at the tree-level. Corrections induced by the WIMP-gluon effective operator, scalar-type WIMP-quark effective operator, and the twist-2 effective operator are calculated. Numerical results show that loop induced spin-independent WIMP-nucleon scattering cross sections are quite considerable in both scenarios.
