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

Journal of High Energy Physics, 2022 The couplings of the Higgs boson (H) with massive gauge bosons of weak interaction (V = W, Z), can be probed in single Higgs boson production at the proposed future Large Hadron-Electron Collider (LHeC).

Stringent bounds on HWW and HZZ anomalous couplings with quantum tomography at the LHC
Journal of High Energy Physics, 2023 Quantum tomography provides the full reconstruction of the density matrix of a state. We use it to study the Higgs boson decay into weak gauge bosons. Anomalous couplings beyond the Standard Model can be constrained by means of observables easily defined

Primary observables for indirect searches at colliders
Journal of High Energy Physics, 2023 We consider the complete set of observables for collider searches for indirect effects of new heavy physics. They consist of SU(3)C × U(1)EM invariant interaction terms/operators that parameterize deviations from the Standard Model.

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

Combined Analysis of CP Properties of Higgs Boson in Effective Higgs Lagrangian [PDF]
Communications in Theoretical Physics, 2016 Summary: CP violation effects of the Higgs stem from not only the CP mixing state but also the CP-violation couplings to electroweak bosons. The two CPV sources are combinedly studied based on an effective Higgs Lagrangian. The constraints from unitarity limits for \(WW\) and \(ZZ\) scatterings are investigated.
