二希格斯双峰模型 (2HDM) 是标准模型最简单的扩展之一。此类模型允许希格斯扇区中的树级 CP 破坏 (CPV)。我们分析了一类 CPV 2HDM（I 型），其中两个希格斯双峰中只有一个与夸克和轻子耦合，避免了危险的风味改变中性流。我们对此类模型的约束条件和大型强子对撞机 (LHC) 预测进行了最新的全面分析。 LHC Run 2 立即感兴趣的是黄金通道，在这里观察到所有三个中性希格斯玻色子衰变成规范玻色子对 WW 和 ZZ，从而提供了 CPV 2HDM 确凿的证据。
Two-Higgs-Doublet Models (2HDMs) are amongst the simplest extensions of the Standard Model. Such models allow for tree-level CP Violation (CPV) in the Higgs sector. We analyse a class of CPV 2HDM (of Type-I) in which only one of the two Higgs doublets couples to quarks and leptons, avoiding dangerous Flavour Changing Neutral Currents. We provide an up to date and comprehensive analysis of the constraints and Large Hadron Collider (LHC) predictions of such a model. Of immediate interest to the LHC Run 2 is the golden channel where all three neutral Higgs bosons are observed to decay into gauge boson pairs, WW and ZZ, providing a smoking gun signature of the CPV 2HDM.
