LEPTOGENESIS IN MODELS WITH MULTI-HIGGS BOSONS [PDF]

open access: yesModern Physics Letters A, 2002
We study the leptogenesis scenario in models with multi-Higgs doublets. It is pointed out that the washing-out process through the effective dimension-five interactions, which has not been taken into account seriously in the conventional scenario, can be effective, and the resultant baryon asymmetry can be exponentially suppressed.

Probing the electroweak final state in type I 2HDM at the LHC

open access: yesJournal 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

Softly broken symmetries in the 2HDM — an invariant formulation

open access: yesJournal 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

The general Two-Higgs Doublet Model in a gauge-invariant form

open access: yesJournal 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

open access: yesJournal 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

Search for the neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at s√=7 TeV with the ATLAS detector [PDF]

open access: yes, 2013
A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron ...

The flavourful present and future of 2HDMs at the collider energy frontier

open access: yesJournal 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

Discovery prospects of a light charged Higgs near the fermiophobic region of Type-I 2HDM

open access: yesJournal 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 ...
