Nondecoupling in multi-Higgs doublet models [PDF]

open access: yesEuropean 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]

open access: yesJournal 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.

Benchmarking di-Higgs production in various extended Higgs sector models

open access: yesJournal of High Energy Physics, 2022
We present a comprehensive study on Higgs pair production in various archetypical extended Higgs sectors such as the real and the complex 2-Higgs-Doublet Model, the 2-Higgs-Doublet Model augmented by a real singlet field and the Next-to-Minimal ...

Flavour alignment in multi-Higgs-doublet models [PDF]

open access: yesJournal 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-

Combined search for the Higgs boson with the D0 experiment [PDF]

open access: yes, 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.

Higgs Boson Studies at the Tevatron [PDF]

open access: yes, 2013
We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90--200 GeV$/c^2$ produced in the gluon-gluon fusion, $WH$, $ZH$, $t{\bar{t}}H$, and vector boson fusion processes, and decaying in the $H ...

Family Symmetries and Multi Higgs Doublet Models [PDF]

open access: yesSymmetry, 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.

τ ± νγγ and to probe the fermiophobic Higgs boson with high cutoff scales

open access: yesJournal of High Energy Physics, 2023
The light fermiophobic Higgs boson h f in the type-I two-Higgs-doublet model can evade the current search programs at the LHC since its production through the quark-antiquark annihilation and gluon fusion is not feasible. The particle can be more elusive
