摘要
With discovery of the 125 GeV boson h(0), the existence of a second doublet is very plausible. We show that the "alignment" phenomenon, that h(0) is found to resemble closely the Standard Model Higgs boson, may correspond to Higgs quartic couplings ni that are O(1) in strength. If the exotic bosom of the second doublet possess extra top Yukawa couplings, which are the least constrained by data, such a two-Higgs-doublet model could drive electroweak baryogenesis, as well as further "protect" the apparent alignment. The exotic Higgs bosom can be sub-TeV in mass while remaining well hidden so far, with broad parameter space for search at the Large Hadron Collider.
