标题： Is the real two-Higgs-doublet model consistent?

摘要： 我们提供了强有力的证据，表明广泛研究的实两希格斯双重模型在重整化下不一致，这是由于夸克引起的发散CP破坏（CPV）。 我们根据发散图的对称性性质，确定了CPV进入重整化群方程的必要要素。 我们证明了虽然这些要素从六环开始存在，但由于近似对称性，该阶的发散CPV为零。 我们表明这些对称性在七环时被破坏，并确定了由此产生的发散CPV的参数依赖性。 显示英文摘要

摘要： We provide strong evidence that the widely-studied real two-Higgs-doublet model is inconsistent under renormalization due to quark-induced divergent CP violation (CPV). We identify the necessary ingredients for the CPV to enter the renormalization-group equations based on symmetry proprieties of the divergent diagrams. We demonstrate that while these ingredients are present starting at six loops, the divergent CPV is zero at that order due to approximate symmetries. We show that these symmetries are broken at seven loops and determine the parameter dependence of the resulting divergent CPV.
