A bstractWe study Higgs and dark matter physics in the type-II two-Higgs-doublet model (2HDM) with an extra U(1)H gauge symmetry, inspired by the E6 grand unified theory (GUT). From the viewpoint of the bottom-up approach, the additional U(1)H gauge symmetry plays a crucial role in avoiding the tree-level flavor changing neutral currents mediated by neutral Higgs bosons in general 2HDMs. In the model with U(1)H gauge symmetry, which has Type-II Yukawa couplings, we have to introduce additional…

Lepton specific two-Higgs-doublet model based on a U(1)X gauge symmetry with dark matter
We discuss a two Higgs doublet model with extra $U(1)_X$ gauge symmetry where lepton specific (type-X) structure for Yukawa interactions is realized by charge assignment of fields under the $U(1)_X$.

We study an extended Standard Model with a gauged U(1)$^{\prime}$ flavor symmetry, motivated not only by the fermion mass hierarchy but also by the excesses in $B \to K^{(*)} l l$ reported by the
Neutrino masses in a two Higgs doublet model with a U(1) gauge symmetry
A bstractGeneral Two Higgs Doublet Models (2HDM) are popular Standard Model extensions but feature flavor changing interactions and lack neutrino masses. We discuss a 2HDM where neutrino masses are
Pseudo-Nambu-Goldstone dark matter and two-Higgs-doublet models
We study a dark matter model with one singlet complex scalar and two Higgs doublets. The scalar potential respects a softly broken global symmetry, which makes the imaginary part of the singlet
