论文摘要
我们重新检查了当前和未来的限制，对重的dialaton构成，耦合到一个简单的黑暗扇区，该黑暗部门由Majorana fermion或Stückelberg矢量场组成。我们包括Dilaton-Higgs混合的三种不同治疗方法，特别注意该模型的规格。此外，我们还邀请读者重新检查矢量暗物质的有效领域理论，我们表明这缺失了重要的术语。除了最新的HIGGS耦合数据，重型标量搜索结果以及暗物质密度/直接检测约束之外，我们研究了该模型的LHC界限，并估算未来HL-LHC和100 TEV FCC Colliders暗物质产生的前景。我们还计算了涉及矢量暗物质，Dilaton和Gluon散射的新型扰动型构造。
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.
