论文摘要
我们对重型DM质量区域中的深色S3模型进行了分析，该模型具有SM的标量扇区的S3对称扩展，其中包括标量$ su（2）$ Doublet Darket Dark Matter候选。除了对模型的参数空间的常规物理约束之外，我们使用公开可用的工具，当今歼灭横截面的Sommerfeld增强因子以及模拟Coma Coma berenices berenices berenices dwarf Galaxy的观察的可能性概况。我们的结果不足以在$ \ sim $ 5 tev以上的群众中，主要是因为暗物质过量生产与遗物丰富的观察不一致。我们还发现一个中等较大的区域，质量在1.2和4.9 TEV之间，该区域可预测DM遗物的正确值，此外，具有sm higgs玻色子特性的光标度（即，在类似于THDM的脱钩极限内）。将结果与模型独立排除曲线的比较和其他CTA模拟的比较表明，这些限制仅在an灭横截面的值中只有一个数量级，以便排除模型的最佳拟合点。
We present an analysis of the Dark S3 model in the heavy DM mass region, this model features an S3 symmetric extension of the scalar sector of the SM including a scalar $SU(2)$ doublet dark matter candidate. We use publicly available tools to compute, in addition to conventional physical constraints on the parameter space of the model, the Sommerfeld enhancement factors for the present day annihilation cross section and the likelihood profile for a simulation of an observation run by the Cherenkov Telescope Array of the Coma Berenices dwarf galaxy. Our results disfavour masses above $\sim$5 TeV mainly because of overproduction of dark matter not consistent with the relic abundance observations; we also find a moderately large region with masses in between 1.2 and 4.9 TeV which predict the correct value of the DM relic and in addition have a light scalar with the characteristics of the SM Higgs boson (i.e. within the decoupling limit akin to the THDM). Comparison of our results with model independent exclusion curves from HESS and other CTA simulations show that these limits fall short only an order of magnitude in the value of the annihilation cross section in order to exclude the best fit point of the model.
