论文摘要
我们提出了对轴突样颗粒（ALP）的新搜索，该颗粒靶向载体玻色子散射（VBS）过程。我们认为非谐振ALP介导的VB，ALP作为脱离壳介质参与其中。每当ALP太轻而无法共同产生时，就会发生此过程，并且它利用ALP相互作用与Electroweak标准模型玻色子的衍生性质。我们研究了$ zz $，$zγ$，$ w^\ pmγ$，$ w^\ pm z $和$ w^\ pm w^\ pm $ pm $ pm $ pm $ pm $ pm $ pm $与大型Diboson不变性群众配对。在仪表不变的框架中工作，通过重新诠释2个公共CMS VBS分析，获得了ALP耦合到Electroweak玻色子的上限。 ALP耦合对$ zz $，$zγ$和$ w^\ pm w^\ pm $ Pairs的约束对ALP质量非常有竞争力。它们具有独立于ALP耦合到粘合剂和ALP衰减宽度的优势。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 propose a new search for Axion-Like Particles (ALPs), targeting Vector Boson Scattering (VBS) processes at the LHC. We consider nonresonant ALP-mediated VBS, where the ALP participates as an off-shell mediator. This process occurs whenever the ALP is too light to be produced resonantly, and it takes advantage of the derivative nature of ALP interactions with the electroweak Standard Model bosons. We study the production of $ZZ$, $Zγ$, $W^\pm γ$, $W^\pm Z$ and $W^\pm W^\pm$ pairs with large diboson invariant masses in association with two jets. Working in a gauge-invariant framework, upper limits on ALP couplings to electroweak bosons are obtained from a reinterpretation of Run 2 public CMS VBS analyses. The constraints inferred on ALP couplings to $ZZ$, $Zγ$ and $W^\pm W^\pm$ pairs are very competitive for ALP masses up to 100 GeV. They have the advantage of being independent of the ALP coupling to gluons and of the ALP decay width. Simple projections for LHC Run 3 and HL-LHC are also calculated, demonstrating the power of future dedicated analyses at ATLAS and CMS.
