We reexamine the minimal Singlet \(+\) Triplet Scotogenic Model, where dark matter is the mediator of neutrino mass generation. We assume it to be a scalar WIMP, whose stability follows from the same \({\mathbb {Z}}_{2}\) symmetry that leads to the radiative origin of neutrino masses. The scheme is the minimal one that allows for solar and atmospheric mass scales to be generated. We perform a full numerical analysis of the signatures expected at dark matter as well as collider experiments. We identify parameter regions where dark matter predictions agree with theoretical and experimental constraints, such as neutrino oscillations, Higgs data, dark matter relic abundance and direct detection searches. We also present forecasts for near future direct and indirect detection experiments. These will further probe the parameter space. Finally, we explore collider signatures associated with the mono-jet channel at the LHC, highlighting the existence of a viable light dark matter mass range.

发散标量暗物质的现象学

我们重新检查最小的Singlet \(+ \) Triplet Scotogenic模型,其中暗物质是中微子质量产生的媒介。我们假设它是一个标量WIMP,其稳定性来自相同的\({\ mathbb {Z}} _ {2} \)导致中微子质量辐射起源的对称性。该方案是最小的方案,允许生成太阳和大气质量标度。我们对暗物质预期的特征以及对撞机实验进行了完整的数值分析。我们确定暗物质预测与理论和实验约束一致的参数区域,例如中微子振荡,希格斯数据,暗物质遗迹丰度和直接检测搜索。我们还提供了对近期直接和间接检测实验的预测。这些将进一步探查参数空间。最后,我们探索了与大型强子对撞机单喷射通道相关的对撞机信号,突出了可行的浅色暗物质质量范围的存在。
