Abstract By borrowing the results from a Large Hadron Collider (LHC) analysis performed with 36.1 fb − 1 of Run 2 data intended to search for A production followed by ZH decay in turn yielding l + l − b b ¯ ( l = e , μ ) final states in the context of the standard four Yukawa types of the 2-Higgs Doublet Model (2HDM), we recast it in terms of sensitivity reaches for the similar process p p → H → Z A → l + l − b b ¯ . This simple exercise across the two processes, which is possible because the only kinematic difference between these are different widths for the Higgs bosons, in turn affecting minimally the efficiency of an experimental selection, enables us to expand the region of parameter space that can be tested to the case when m H ≥ m A + m Z . Furthermore, we extrapolate our results to full Run 3 data samples. We conclude that, while the high energy and luminosity stage of the LHC can afford one with increased sensitivity to the 2HDM in general, the recast analysis does not add anything to what already probed through the actual one.

将 pp→A→ZH→l+l−bb¯ 和 pp→H→ZA→l+l−bb¯ 当前和未来搜索映射到 2HDM 参数空间

摘要 通过借用大型强子对撞机 (LHC) 分析的结果,运行 2 数据的 36.1 fb − 1 旨在搜索 A 产生,然后 ZH 衰变依次产生 l + l − bb ¯ ( l = e , μ )在标准四种 Yukawa 类型的 2-Higgs 双峰模型 (2HDM) 的上下文中的最终状态,我们根据类似过程 pp → H → ZA → l + l − bb ¯ 的灵敏度范围对其进行重新定义。这个跨越两个过程的简单练习是可能的,因为它们之间唯一的运动学差异是希格斯玻色子的宽度不同,反过来对实验选择的效率影响最小,使我们能够扩展可以测试的参数空间区域对于 m H ≥ m A + m Z 的情况。此外,我们将结果外推到完整的 Run 3 数据样本。我们得出的结论是,
