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.

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

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.

Grand Unification in Higher Dimensions [PDF]

, 2002
We have recently proposed an alternative picture for the physics at the scale of gauge coupling unification, where the unified symmetry is realized in higher dimensions but is broken locally by a symmetry breaking defect.

Crosschecks for Unification at the LHC [PDF]

, 2009
Experiments at the Large Hadron Collider (LHC) might test the picture of supersymmetric Grand Unification in particle physics. We argue that the identification of gaugino masses is the most promising step in this direction.

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 ...

Grand Unification of Flavor Mixings [PDF]

, 2012
An origin of flavor mixings in quark and lepton sectors is still a mystery, and a structure of the flavor mixings in lepton sector seems completely different from that of quark sector.

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.

More on fake GUT

Journal of High Energy Physics, 2022
It is remarkable that the matter fields in the Standard Model (SM) are apparently unified into the SU(5) representations. A straightforward explanation of this fact is to embed all the SM gauge groups into a simple group containing SU(5), i.e., the grand

Dark matter in E 6 Grand unification

Journal of High Energy Physics, 2018
We discuss fermionic dark matter in non-supersymmetric E 6 Grand Unification. The fundamental representation of E 6 contains, in addition to the standard model fermions, exotic fermions and we argue that one of them is a viable, interesting dark matter ...
