Gravitational Wave Imprints of a High-Quality Axion and the Origin of Flavor Hierarchies
K. S. Babu, Sai Charan Chandrasekar, Sudip Jana +1
Axions, arising from an anomalous global Peccei-Quinn symmetry , offer a compelling solution to the strong CP problem but are vulnerable to Planck-suppressed oper…

Fermion Mass Hierarchy and a High Quality Axion From Gauged U(1) Flavor Symmetry
K. S. Babu, Sai Charan Chandrasekar, Zurab Tavartkiladze
We present a class of models based on a gauged flavor symmetry that explains the hierarchical structure of fermion masses and mixings via the Froggatt-Nielsen (FN) mechani…
