摘要:

我们重新审视当前和未来的限制重的费米子耦合到一个简单的暗部门组成的马约拉纳费米子或Stückelberg矢量场。我们包括三种不同的治疗的玻色子-希格斯混合,特别注意规范不变的制定模型。此外,我们还邀请读者重新审视矢量暗物质的有效场论,我们发现这些理论缺少重要的术语。随着最新的Higgs耦合数据,重标量搜索结果,和暗物质密度/直接检测的限制,我们研究的LHC边界上的模型和估计的前景暗物质生产在未来的HL-LHC和100 TeV FCC对撞机。我们还计算了新的微扰么正性约束,涉及矢量暗物质,胶子和胶子散射。

英文摘要:

We re-examine current and future constraints on a heavy dilaton coupled to a simple dark sector consisting of a Majorana fermion or a Stückelberg vector field. We include three different treatments of dilaton-Higgs mixing, paying particular attention to a gauge-invariant formulation of the model. Moreover, we also invite readers to re-examine effective field theories of vector dark matter, which we show are missing important terms. Along with the latest Higgs coupling data, heavy scalar search results, and dark matter density/direct detection constraints, we study the LHC bounds on the model and estimate the prospects of dark matter production at the future HL-LHC and 100 TeV FCC colliders. We additionally compute novel perturbative unitarity constraints involving vector dark matter, dilaton and gluon scattering.
