We present new variants of the two-Higgs-doublet model where all Yukawa couplings with physical Higgs bosons are controlled by the quark mixing matrices of both chiralities, as well as, in one case, the ratio between the two scalar doublets' vacuum expectation values. We obtain these by imposing approximate symmetries on the Lagrangian which, in one of the cases, clearly reveals the model to be the electroweak remnant of the minimal left-right symmetric model. We also argue for the benefits of the bidoublet notation in the two-Higgs-doublet model context for uncovering new models. © 2020 authors. Published by the American Physical Society.
