Accidental Peccei-Quinn Symmetry From Gauged U(1) and a High Quality Axion
K. S. Babu, Bhaskar Dutta, Rabindra N. Mohapatra
We construct explicit models that solve the axion quality problem originating from quantum gravitational effects. The general strategy we employ is to supplement the Standard Model…

Hybrid SO(10) Axion Model Without Quality Problem
K. S. Babu, Bhaskar Dutta, Rabindra N. Mohapatra
Invisible axion models that solve the strong CP problem via the Peccei-Quinn (PQ) mechanism typically have a quality problem that arises from quantum gravity effects which violate…
