来自电弱单线态的直接信号通过希格斯门

Direct signals from electroweak singlets through the Higgs portal

Rainer Dick

摘要:

在冻结产生标准热的假设下,我们回顾了希格斯门暗物质核反冲信号的预测和约束。热产生的标量和矢量希格斯门暗物质质量被限制在共振区附近的希格斯质量的一半或几个TeV以上。这些模型的共振区域将由XENONNT和LZ进行测试。DarkSide-20 k和DARWIN可以测试到幺正性极限的全部质量范围。具有纯CP奇耦合的费米子希格斯门暗物质受到希格斯衰变宽度的限制,但具有强烈抑制的反冲截面,这无法用即将到来的实验进行测试。通过直接搜索实验,可以限制具有CP偶希格斯耦合和奇希格斯耦合组合的费米子希格斯门暗物质。

英文摘要:

We review predictions and constraints for nuclear recoil signals from Higgs portal dark matter under the assumption of standard thermal creation from freeze-out. Thermally created scalar and vector Higgs portal dark matter masses are constrained to be in the resonance region near half the Higgs mass or above several TeV. The resonance region for these models will be tested by XENONnT and LZ. The full mass range up to the unitarity limit can be tested by DarkSide-20k and DARWIN. Fermionic Higgs portal dark matter with a pure CP odd coupling is constrained by the Higgs decay width, but has strongly suppressed recoil cross sections which cannot be tested with upcoming experiments. Fermionic Higgs portal dark matter with a combination of CP even and odd Higgs couplings can be constrained by the direct search experiments.
