WIMP的直接探测

Direct detection of WIMPs

David G. Cerdeno, Anne M. Green

摘要:

一般的弱相互作用大质量粒子(WIMP)是解释我们宇宙中冷暗物质的最有吸引力的候选者之一,因为它将以正确的丰度热产生,以解释观测到的暗物质密度。WIMP可以直接通过其与目标材料的弹性散射来搜索,并且目前正在进行或计划进行各种实验。在这些笔记中,我们概述了WIMP的直接检测率的理论计算以及不同的检测信号。我们讨论了各种成分(从粒子物理学和天体物理学),进入计算,并审查在粒子物理模型中直接检测WIMP的理论预测。

英文摘要:

A generic weakly interacting massive particle (WIMP) is one of the most attractive candidates to account for the cold dark matter in our Universe, since it would be thermally produced with the correct abundance to account for the observed dark matter density. WIMPs can be searched for directly through their elastic scattering with a target material, and a variety of experiments are currently operating or planned with this aim. In these notes we overview the theoretical calculation of the direct detection rate of WIMPs as well as the different detection signals. We discuss the various ingredients (from particle physics and astrophysics) that enter the calculation and review the theoretical predictions for the direct detection of WIMPs in particle physics models.
