论文摘要
我们在DILATON有效场理论的背景下构建了一个复合的两-higgs-doublet模型（2HDM）。此EFT描述了在几乎符合$ su（3）$量规场理论的晶格模拟中观察到的粒子谱。第二个Higgs Doublet自然可容纳在EFT中，以前用于构建一higgs doublet模型。我们探讨了现象学和EFT要求的相互作用，并补充了来自$ su（3）$ gauge理论的数值晶格研究的信息，并带有八个基本（DIRAC）费米子。我们构建了一个可行的模型，该模型具有中等的参数调整。在参数空间的相关部分中，我们将模型与2HDM的常规一般描述匹配，并评论标量势中的托管对称性（断裂）的作用。对Precision Electroweak参数$ t $的贡献为CDF II对W-Boson质量的最新测量提供了可能的解释。
We construct a composite two-Higgs-doublet model (2HDM) within the context of dilaton effective field theory. This EFT describes the particle spectrum observed in lattice simulations of a near-conformal $SU(3)$ gauge field theory. A second Higgs doublet is naturally accommodated within the EFT, used previously to construct a one-Higgs-doublet model. We explore the interplay of phenomenological and EFT requirements, supplemented by information from numerical lattice studies of the $SU(3)$ gauge theory with eight fundamental (Dirac) fermions. We build a viable model with moderate parameter tuning. In the relevant portion of parameter space, we match the model to a conventional general description of 2HDMs, and comment on the role of custodial symmetry (breaking) in the scalar potential. Contributions to the precision electroweak parameter $T$ provide a possible explanation for the recent measurement of the W-boson mass by CDF II.
