W boson mass anomaly and grand unification

Physics Letters B, 2022
It is known that the recently reported shift of the W boson mass can be easily explained by an SU(2)L triplet Higgs boson with a zero hypercharge if it obtains a vacuum expectation value (VEV) of O(1) GeV.

Special grand unification [PDF]

Progress of Theoretical and Experimental Physics, 2017
We discuss new-type grand unified theories based on grand unified groups broken to their special subgroups as well as their regular subgroups. In the framework, when we construct four-dimensional (4D) chiral gauge theories, i.e., the Standard Model (SM), 4D gauge anomaly cancellation restricts the minimal number of generations of the 4D SM Weyl ...

Effective Higgs theories in supersymmetric grand unification

European Physical Journal C: Particles and Fields, 2017
The effective Higgs theories at the TeV scale in supersymmetric $$\mathrm{SU}(5)$$ SU ( 5 ) grand unification models are systematically derived. Restricted to extensions on $$\mathbf {5}_{H}$$ 5 H containing the Higgs sector we show that only two types ...

331 models and grand unification: From minimal SU(5) to minimal SU(6)

Physics Letters B, 2016
We consider the possibility of grand unification of the SU(3)c⊗SU(3)L⊗U(1)X model in an SU(6) gauge unification group. Two possibilities arise. Unlike other conventional grand unified theories, in SU(6) one can embed the 331 model as a subgroup such that

Proton lifetime in minimal SUSY SU(5) in light of LHC results

Journal of High Energy Physics, 2022
We examine proton decay mediated by color-triplet Higgsinos in minimal supersymmetric SU(5) grand unified theory in light of the discovery of the Higgs boson and the absence of SUSY signals at the LHC.

Road map through the desert with scalars

Journal of High Energy Physics, 2022
In the context of the gauge coupling unification, we present a comprehensive analysis of the extensions of the Standard Model with vector-like fermions and scalars.

Two-Higgs-doublet model and quark-lepton unification

Journal of High Energy Physics, 2022
We study the Two-Higgs-Doublet Model predicted in the minimal theory for quark-lepton unification that can describe physics at the low scale. We discuss the relations among the different decay widths of the new Higgs bosons and study their phenomenology ...

Fermion hierarchies in SU(5) grand unification from Γ 6 ′ $$ {\Gamma}_6^{\prime } $$ modular flavor symmetry

Journal of High Energy Physics, 2023
We construct an SU(5) grand unified model in which the hierarchies of the quark and lepton masses and mixing are explained by the Γ 6 ′ $$ {\Gamma}_6^{\prime } $$ modular flavor symmetry.
