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…
"An SO(10) Solution to the Puzzle of Quark and Lepton Masses"
K. S. Babu, S. M. Barr
It is shown that almost all features of the quark and lepton masses can be satisfactorily and simply explained without family symmetry, including the threefold mass hierarchy among…
A Solution to the Small Phase Problem of Supersymmetry
K. S. Babu, S. M. Barr
It is a well--known problem that in supersymmetric models there are new CP--violating phases which, if unsuppressed, would give a neutron electric dipole moment to ti…
Natural Suppression of Higgsino-Mediated Proton Decay in Supersymmetric SO(10)
K. S. Babu, S. M. Barr
In supersymmetric Grand Unified Theories, proton decay mediated by the color--triplet higgsino is generally problematic and requires some fine--tuning of parameters. We present a m…
