We analyze CP-violating effects in both Electric Dipole Moment (EDM) measurements and future analyses at the Large Hadron Collider (LHC) assuming a 2-Higgs-Doublet Model (2HDM) with "soft’’ CP-violation. Our analysis of EDMs and current LHC constraints shows that, in the case of a 2HDM Type II and Type III, an 𝒪(0.1) CP-violating phase in the Yukawa interaction between H1 (the 125GeV Higgs boson) and fermions is still allowed. For these scenarios, we study CP-violating effects in the neutron EDM and ttH1 production at the LHC. Our analysis shows that such an 𝒪(0.1) CP-violating phase can be easily confirmed or excluded by future neutron EDM tests, with LHC data providing a complementary cross-check.

面对电偶极矩和对撞机的带有SoftCPviolation的两希格斯双峰模型

我们在电偶极矩(EDM)测量和大型强子对撞机(LHC)的未来分析中都分析了违反CP的影响,假设2-Higgs-Doublet模型(2HDM)具有“柔和” CP违反。当前的LHC约束条件表明,对于2HDM II型和III型, 𝒪0.1 CP违反阶段在汤川之间的相互作用 H1个125GËV希格斯玻色子)和费米子仍然被允许。对于这些情况,我们研究了中子EDM和ŤŤH1个大型强子对撞机的生产。我们的分析表明,这样的𝒪0.1 违反CP的阶段很容易被以后的中子EDM测试确认或排除,LHC数据提供了补充的交叉核对。
