Abstract: A bstractSU(5) ⊗ SU(5) provides a minimal grand unification scheme for fermions and gauge forces if there are vector-like quarks and leptons in nature. We explore the gauge coupling unification in a non-supersymmetric model of… read more here.

Abstract: The dark dimension scenario, predicting one extra mesoscopic dimension in the micron range, has emerged by applying various swampland principles to the dark energy. In this note we find that realizing the grand unification of… read more here.

DOI: 10.1103/physrevd.111.095013
Abstract: We examine the vacuum stability of gauge symmetry breaking in five dimensions, compactified on the S1/(Z2×Z2′) orbifold. We consider SU(N), Sp(N), SO(2N), and SO(2N+1) theories in the bulk, and provide an exhaustive classification of possible… read more here.

DOI: 10.1103/physrevd.98.095011
Abstract: We propose a minimal realization of the Peccei-Quinn mechanism in a realistic SU(5) model, where the axion mass is directly connected to the grand unification scale. Accounting for constraints from proton decay, collider searches and… read more here.

DOI: 10.1142/s021988782150225x
Abstract: In this short note, we will prove in a few steps that the new tetrads introduced previously in Einstein–Maxwell–Yang–Mills four-dimensional Lorentzian spacetimes where gravitational and Yang–Mills fields are present contain both the necessary information to… read more here.
