Asymmetric Orbifolds and Grand Unification [PDF]
Physical Review D, 1996 We generalize the rules for the free fermionic string construction to include other asymmetric orbifolds with world-sheet bosons. We use these rules to construct various grand unified string models that involve level-3 current algebras.

Holographic grand unification [PDF]
Journal of High Energy Physics, 2006 We present a framework for grand unification in which the grand unified symmetry is broken spontaneously by strong gauge dynamics, and yet the physics at the unification scale is described by (weakly coupled) effective field theory. These theories are formulated, through the gauge/gravity correspondence, in truncated 5D warped spacetime with the UV and

Axion couplings in grand unified theories
Journal of High Energy Physics, 2022 We show that the couplings of axions to gauge bosons are highly restricted in Grand Unified Theories where the standard model is embedded in a simple 4D gauge group.

Systematic classification of aGUT models in five dimensions: the SU(N) kinship
Journal of High Energy Physics, 2023 Asymptotic Grand Unification theories (aGUTs) in five dimensions provide a valid alternative to standard quantitative unification. We define the pathway towards viable models starting from a general unified bulk gauge symmetry.

SU(5) grand unification and W-boson mass
Physics Letters B, 2023 A realistic extension of the minimal SU(5) theory consisting of the addition of an adjoint fermion is known to predict light real fermion and scalar weak triplets, potentially accessible at the LHC.

Model building by coset space dimensional reduction scheme using eight-dimensional coset spaces
Journal of High Energy Physics, 2023 We investigate the twelve-dimensional gauge-Higgs unification models with an eight- dimensional coset space as the extra space. For each model, we apply the coset space dimensional reduction procedure and examine the particle contents of the resulting ...

Topological Grand Unification [PDF]
, 2009 We propose a new grand unification scenario for ensuring proton stability and triplet-doublet Higgs mass splitting with the help of topological symmetry and dynamics.Comment: 9 pages, version to appear in ...

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.
