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 ...

Softly broken symmetries in the 2HDM — an invariant formulation
Journal of High Energy Physics, 2023 Soft breaking of a symmetry requires an invariance of the dimension-4 part of the Lagrangian and non-trivial variation of the lower-dimensional part. However, in general, separation between the dim-4 and lower-dimensional Lagrangian is not invariant with

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

Probing the electroweak final state in type I 2HDM at the LHC
Journal of High Energy Physics, 2023 Most of the experimental searches of the non-Standard Model Higgs boson(s) at the LHC rely on the QCD induced production modes. However, in some beyond Standard Model frameworks, the additional Higgs bosons can have fermiophobic behaviour. The type I two

Discovery prospects of a light charged Higgs near the fermiophobic region of Type-I 2HDM
Journal of High Energy Physics, 2023 Determining if the SM-like Higgs is part of an extended Higgs sector is the most important question to be asked after discovery. A light charged Higgs boson with mass smaller than the sum of top and bottom quarks is naturally allowed in Type-I two Higgs ...

The general Two-Higgs Doublet Model in a gauge-invariant form
Journal of High Energy Physics, 2022 In the general Two-Higgs Doublet Model it has been shown that the Higgs potential can be expressed in terms of gauge-independent quantities that transform covariantly under unitary mixing of the doublets.

Exploring wrong sign scenarios in the Yukawa-Aligned 2HDM
Journal of High Energy Physics, 2023 We discuss scenarios with wrong-sign (WS) Yukawa couplings for the discovered Higgs boson in the Yukawa-aligned two Higgs doublet model. In the WS scenario, Yukawa couplings for down-type quarks and/or charged leptons have an opposite sign as compared to

The flavourful present and future of 2HDMs at the collider energy frontier
Journal of High Energy Physics, 2022 We study the intersection of flavour and collider physics for Two-Higgs-Doublet models of Type I and II. Drawing from the flavour precision-LHC exotics search complementarity, we also provide a projection of the future sensitivity that can be achieved in

Unitarity bounds on extensions of Higgs sector
Journal of High Energy Physics, 2023 It is widely believed that extensions of the minimal Higgs sector is one of the promising directions for resolving many puzzles beyond the Standard Model (SM).
