The WIMP proposed here yields the observed abundance of dark matter, and is consistent with the current limits from direct detection, indirect detection, and collider experiments, if its mass is $\sim 72$ GeV/c 2. It is also consistent with analyses of the gamma rays observed by Fermi-LAT from the Galactic center (and other sources), and of the antiprotons observed by AMS-02, in which the excesses are attributed to dark matter annihilation. These successes are shared by the inert doublet model (IDM), but the phenomenology is very different: the dark matter candidate of the IDM has first-order gauge couplings to other new particles, whereas the present candidate does not. In addition to indirect detection through annihilation products, it appears that the present particle can be observed in the most sensitive direct-detection and collider experiments currently being planned.

新暗物质 WIMP 的实验特征

这里提出的 WIMP 产生了观察到的暗物质丰度,并且与直接检测、间接检测和对撞机实验的当前限制一致,如果其质量为$\sim 72$ GeV/ c 2. 这也与 Fermi-LAT 从银河中心(和其他来源)观察到的伽马射线以及 AMS-02 观察到的反质子的分析一致,其中过量归因于暗物质湮灭。惰性双峰模型 (IDM) 也取得了这些成功,但现象学非常不同:IDM 的暗物质候选者与其他新粒子具有一阶规范耦合,而目前的候选者则没有。除了通过湮灭产物的间接探测外,目前正在计划的最灵敏的直接探测和对撞机实验中似乎可以观察到目前的粒子。
