Charge-breaking domain walls separating neutral vacua in multi-Higgs models [PDF]
Physical Review DThe scalar potential of a multi-Higgs model can possess a rich structure of minima and saddle points, which evolves in an intricate way as the parameters change.

CP violation in multi-Higgs supersymmetric models [PDF]
Nuclear Physics B, 1996 We consider supersymmetric extensions of the standard model with two pairs of Higgs doublets. We study the possibility of spontaneous $CP$ violation in these scenarios and present a model where the origin of $CP$ violation is soft, with all the complex phases in the Lagrangian derived from complex masses and vacuum expectation values (VEVs) of the ...

Multi-representation dynamics of SU(4) composite Higgs models: chiral limit and spectral reconstructions [PDF]
The European Physical Journal C, 2022 We present a lattice study of the SU (4) gauge theory with two Dirac fermions in the fundamental and two in the two-index antisymmetric representation, a model close to a theory of partial compositeness proposed by G. Ferretti. Focus of this work are the

Pseudoscalar MSSM Higgs Production at NLO SUSY-QCD
Journal of High Energy Physics, 2023 One of the most important mechanisms at the Large Hadron Collider (LHC) for the production of the pseudoscalar Higgs boson of the Minimal Supersymmetric Standard Model (MSSM) is the loop-induced gluon fusion process gg → A.

CP-odd invariants for multi-Higgs models and applications with discrete symmetry [PDF]
, 2016 CP-odd invariants provide a basis independent way of studying the CP properties of Lagrangians. We propose powerful methods for constructing basis invariants and determining whether they are CP odd or CP even, then systematically construct all of the ...

Nonstandard Yukawa Couplings and Higgs Portal Dark Matter [PDF]
, 2015 We study the implications of non-standard Higgs Yukawa couplings to light quarks on Higgs-portal dark matter phenomenology. Saturating the present experimental bounds on up-quark, down-quark, or strange-quark Yukawa couplings, the predicted direct dark ...

Flavor physics in the multi-Higgs doublet models induced by the left-right symmetry [PDF]
Journal of High Energy Physics, 2018 A bstractIn this paper, we discuss the multi-Higgs doublet models, that could be effectively induced by the extended Standard Model (SM). In particular, we focus on the phenomenology in the supersymmetric model with left-right (LR) symmetry, where the ...

, 1992 We investigate the possibility of a multi-Higgs doublet model where the lightest neutral Higgs boson ($h^0$) decouples from the fermion sector. We are partially motivated by the four $\ell^+\ell^-\gamma\gamma$ events with $M_{\gamma\gamma}\simeq60$\,GeV ...

Multi-Higgs doublet models: physical parametrization, sum rules and unitarity bounds [PDF]
Journal of High Energy Physics, 2017 A bstractIf the scalar sector of the Standard Model is non-minimal, one might expect multiple generations of the hypercharge-1/2 scalar doublet analogous to the generational structure of the fermions.

3HDM with ∆(27) symmetry and its phenomenological consequences
Journal of High Energy Physics, 2023 We perform a comprehensive analysis of a version of the 3-Higgs doublet model whose scalar potential is invariant under a global ∆(27) discrete symmetry and where the three scalar doublets are chosen to transform as a triplet under this discrete group ...
