用ATLAS探测器在$\sqrt{s} = 13$ TeV上寻找质子-质子碰撞中全轻子末态的共振$WZ$产生

Search for resonant $WZ$ production in the fully leptonic final state in proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

ATLAS Collaboration

摘要:

在全轻子通道(电子和μ子)中寻找衰减为$WZ$的重共振。它是基于质子-质子碰撞数据收集的ATLAS实验在大型强子对撞机在一个中心的质量能量为13 TeV,对应的积分亮度为36.1 fb $^{-1}$。没有观察到明显超过标准模型的预测和限制的生产截面倍分支比的重矢量粒子产生的夸克-反夸克融合或通过矢量玻色子融合。约束也得到了一个单电荷希格斯玻色子的质量和耦合,在Georgi-Machacek模型,通过矢量玻色子融合产生。

英文摘要:

A search for a heavy resonance decaying into $WZ$ in the fully leptonic channel (electrons and muons) is performed. It is based on proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 36.1 fb$^{-1}$. No significant excess is observed over the Standard Model predictions and limits are set on the production cross section times branching ratio of a heavy vector particle produced either in quark-antiquark fusion or through vector-boson fusion. Constraints are also obtained on the mass and couplings of a singly charged Higgs boson, in the Georgi-Machacek model, produced through vector-boson fusion.
