A very likely New Physics in plain sight, but that the community does not see, is a second Higgs doublet that has a second set of Yukawa couplings. The extra tt and tc couplings can each drive baryogenesis, with O(1) Higgs quartic couplings providing a first order electroweak phase transition. A natural cancellation mechanism can tame electron EDM, if extra ee, tt couplings “know” the known fermion mass and mixing hierarchies. Colliding c with g produces tH/A, bH${}^{+}$ via extra tc coupling, and together with extra tt coupling give ttc(bar), ttt(bar), and btb(bar) signatures at the LHC. Extra tu coupling can also be probed, but more definitive would be the B to $\mu \nu$ and $\tau \nu$ decay rate ratio. Myriad extra Yukawa couplings can make an impact on flavor physics and CP violation, including on muon g-2. The opening to the prelude of a new physics Higgs and flavor era may unfold before us.

第二个希格斯双峰的额外顶部 Yukawa 耦合

一个很可能是显而易见但社区没有看到的新物理学，是具有第二组 Yukawa 耦合的第二个希格斯双峰。额外的tt和tc耦合可以分别驱动重核发生，其中 O(1) 希格斯四次耦合提供一阶电弱相变。如果额外的ee，tt耦合“知道”已知的费米子质量和混合层次，自然抵消机制可以驯服电子 EDM。c与g碰撞产生tH/A, bH${}^{+}$通过额外的tc耦合，并与额外的tt耦合一起在 LHC 上给出ttc（bar）、ttt（bar）和btb（bar）签名。也可以探测额外的tu耦合，但更明确的是 B to$\mu \nu$和$\tau \nu$衰减率比。无数额外的 Yukawa 耦合可以对风味物理和 CP 违规产生影响，包括对 muon g-2 的影响。一个新的物理希格斯和风味时代的序幕可能会在我们面前展开。
