Toward a Unified Axion Cosmology
Takeshi Fukuyama
We explore a unified axion framework connecting grand unification, string-inspired axion-like particles (ALPs), and cosmology. Starting from the QCD axion associated with Peccei--Q…

Updated analysis of minimal supersymmetric SO(10) with a universal soft spectrum
Cheng-Wei Chiang, Takeshi Fukuyama
We update the analysis of minimal supersymmetric $\SO{10}$ grand unification with a universal, constrained-MSSM-like soft-breaking spectrum. A pair of Yukawa matrices in the $\rep{…

Axion in the minimal SO(10) GUT
Takeshi Fukuyama
The QCD axion is investigated within the minimal supersymmetric SO(10) grand unified theory, where the Yukawa sector involves Higgs multiplets and .…
