论文摘要
我们研究了通过用惰性$ \ mathrm {su}（2）_ \ mathrm {l} $ sextuplet sextar seartar构建的标准模型构建的暗物质模型。六分光组件被六链和希格斯双线之间的四分之一耦合分开，而electroweak对称性破裂后，导致一个黑暗的扇形，带有一个带有三重电荷的带电，两个双电荷，两个单打充电和两个中性标量的标量。较轻的中性标量玻色子充当暗物质粒子。我们从$ \ text {monoJet} + /\！\！\！当前的Electroweak Precision测试。此外，我们估计了100 tev $ pp $对撞机的预计灵敏度和未来的$ e^+e^ - $ collider，并发现此类未来的项目可以探索TEV质量规模。尽管如此，如果暗物质颗粒仅起源于热产生，这种质量尺度仅对应于观察到的遗物丰度的一个亚尺寸成分。
We study a dark matter model constructed by extending the standard model with an inert $\mathrm{SU}(2)_\mathrm{L}$ sextuplet scalar of hypercharge 1/2. The sextuplet components are split by the quartic couplings between the sextuplet and the Higgs doublet after electroweak symmetry breaking, resulting in a dark sector with one triply charged, two doubly charged, two singly charged, and two neutral scalars. The lighter neutral scalar boson acts as a dark matter particle. We investigate the constraints on this model from the $\text{monojet} + /\!\!\!\!E_\mathrm{T}$ and $\text{soft-dilepton} + \text{jets} + /\!\!\!\!E_\mathrm{T}$ searches at the 13 TeV Large Hadron Collider, as well as from the current electroweak precision test. Furthermore, we estimate the projected sensitivities of a 100 TeV $pp$ collider and of a future $e^+e^-$ collider, and find that such future projects could probe TeV mass scales. Nonetheless, such mass scales only correspond to a subdominant component of the observed relic abundance if the dark matter particles solely originate from thermal production.
