UV-Complete Models for a Light Axial Gauge Boson
Bhaskar Dutta, Aparajitha Karthikeyan, Rabindra N. Mohapatra
We present new anomaly free gauge models where the gauge field only has axial vector couplings to both quarks and leptons. We use the left-right symmetric universal seesaw models a…

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…
