论文摘要
我们考虑完整的前阶 - 尺寸五 - 有效的阿尔卑斯山线性线性拉格朗日。得出了对ALP-SM有效耦合的全套一环贡献，包括所有有限校正。这些计算的一些现象学后果也被探讨为插图，在fermions的情况下，有风味对角线通道：尤其是，我们探索了关于ALP与顶级夸克的耦合的一环约束。此外，我们建议对Alps进行新的搜索，以LHC为目标VBS过程。为此，我们考虑了VBS中的树级Diboson生产，ALP作为脱离核心中介。 ALP EW耦合的上限是通过对2个公共CMS VBS分析的重新解释获得的。还计算了针对LHC运行3和HL-LHC的简单预测，证明了Atlas和CMS未来专用分析的力量。
We consider the complete leading-order -- dimension five -- effective linear Lagrangian for ALPs. The full set of one-loop contributions to ALP-SM effective couplings are derived, including all finite corrections. A few phenomenological consequences of these computations are also explored as illustration, with flavour diagonal channels in the case of fermions: in particular, we explore one-loop constraints on the coupling of the ALP to top quarks. Additionally, we propose a new search for ALPs, targeting VBS processes at the LHC. For this, we consider the tree-level diboson production in VBS, where the ALP participates as an off-shell mediator. Upper limits on ALP EW couplings are obtained from a reinterpretation of Run 2 public CMS VBS analyses. Simple projections for LHC Run 3 and HL-LHC are also calculated, demonstrating the power of future dedicated analyses at ATLAS and CMS.
