Nondecoupling in multi-Higgs doublet models [PDF]
European Physical Journal C: Particles and Fields, 2020 We consider models with any number of Higgs doublets and study the conditions for decoupling. We show that, under very general circumstances, all the quadratic coefficients of the scalar potential must be present, except in special cases, which include ...

Multi-Higgs-doublet models and singular alignment [PDF]
Journal of High Energy Physics, 2019 We consider a 4-Higgs-doublet model in which each Higgs doublet gives mass to one of the fermion sets {m t }, {m b , m τ , m c }, {m μ , m s }, and {m d , m u , m e }. The sets have the feature that within each of them the masses are similar.

Flavour alignment in multi-Higgs-doublet models [PDF]
Journal of High Energy Physics, 2017 Extended electroweak scalar sectors containing several doublet multiplets require flavour-aligned Yukawa matrices to prevent the appearance at tree level of unwanted flavour-changing neutral-current transitions. We analyse the misalignment induced by one-

Minima of multi-Higgs potentials with triplets of Î(3n2) and Î(6n2)
Physics Letters B, 2017 We analyse the minima of scalar potentials for multi-Higgs models where the scalars are arranged as either one triplet or two triplets of the discrete symmetries A4, S4, Î(27), Î(54), as well as Î(3n2) and Î(6n2) with n>3.

Two Higgs Doublets, a 4th Generation and a 125 GeV Higgs: A Review [PDF]
Advances in High Energy Physics, 2013 We review the possible role that multi-Higgs models may play in our understanding of the dynamics of a heavy 4th sequential generation of fermions. We describe the underlying ingredients of such models, focusing on two Higgs doublets, and discuss how ...

Symmetries of the scalar sector of multi-Higgs-doublet models [PDF]
, 2012 In pursuit of the origin of the masses of particles in the Standard Model, the Brout- Englert-Higgs Mechanism predicts the existence of a scalar boson, whose discovery has been the main goal of the Large Hadron Collider. However, introducing this scalar boson does not provide the answer to all inadequacies of the Standard Model.

Combined search for the Higgs boson with the D0 experiment [PDF]
, 2013 We perform a combination of searches for standard model Higgs boson production in $p\bar{p}$ collisions recorded by the D0 detector at the Fermilab Tevatron Collider at a center of mass energy of $\sqrt{s}=1.96$ TeV.

Family Symmetries and Multi Higgs Doublet Models [PDF]
Symmetry, 2020 Imposing a family symmetry on the Standard Model in order to reduce the number of its free parameters, due to the Schur’s Lemma, requires an explicit breaking of this symmetry. To avoid the need for this symmetry to break, additional Higgs doublets can be introduced.
