Higgs potential and fundamental physics [PDF]
European Journal of Physics, 2017 Physics associated with the Higgs field potential is rich and interesting and deserves a concise summary for a broader audience to appreciate the beauty and the challenges of this subject. We discuss the role of the Higgs potential in particle physics, in particular in the spontaneous symmetry breaking and in the mass generation using an example of a ...

Precise calculations for decays of Higgs bosons in extended Higgs sectors [PDF]
arXivWe briefly introduce H-COUP_3.0, which we developed for evaluating higher-order corrections to any Higgs boson decays in various extended Higgs sectors. Focusing on two Higgs doublet models (2HDMs), we then discuss how the non-decoupling effects of the additional Higgs bosons are significant in Higgs boson decays.

Studies on Extended Higgs Sectors as a Probe of New Physics Beyond the Standard Model [PDF]
arXiv, 2012 In this thesis, we discuss theoretical properties of various Higgs sectors, and we analyze constraints from current experimental data, and then we study collider signatures in each Higgs sector. In Part I, we focus on the phenomenology of various extended Higgs sectors such as the two Higgs doublet model, the Higgs triplet model and Higgs sectors in ...

Off-shell Higgs couplings in H⁎ → ZZ → ℓℓνν
Physics Letters B, 2021 We explore the new physics reach for the off-shell Higgs boson measurement in the pp→H⁎→Z(ℓ+ℓ−)Z(νν¯) channel at the high-luminosity LHC. The new physics sensitivity is parametrized in terms of the Higgs boson width, effective field theory framework, and

Finite quark-mass effects in Higgs boson production with dijets at large energies
Journal of High Energy Physics, 2019 The production of a Higgs boson in association with at least two jets receives contributions both from the fusion of weak vector bosons (VBF) and from QCD processes, especially gluon fusion (GF). The former process is important for measuring the coupling

A UV complete compositeness scenario: LHC constraints meet the lattice
Journal of High Energy Physics, 2017 We investigate a recently proposed UV-complete composite Higgs scenario in the light of the first LHC runs. The model is based on a SU(4) gauge group with global flavour symmetry breaking SU(5) → SO(5), giving rise to pseudo Nambu-Goldstone bosons in ...

The scale of new physics from the Higgs couplings to gg
Physics Letters B, 2022 Measuring the Higgs couplings accurately at colliders is one of the best routes for finding physics Beyond the Standard Model (BSM). If the measured couplings deviate from the SM predictions, then this would give rise to energy-growing processes that ...

Non-Minimal Higgs Sectors: The Decoupling Limit and its Phenomenological Implications, [PDF]
arXiv, 1995 In models with a non-minimal Higgs sector, a decoupling limit can be defined. In this limit, the masses of all the physical Higgs states are large (compared to the scale of electroweak symmetry breaking) except for one neutral CP-even Higgs scalar, whose properties are indistinguishable from the Higgs boson of the minimal Standard Model. The decoupling
