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…
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…
Theory of Neutrinos
R. N. Mohapatra, S. Antusch, K. S. Babu +29
After a brief overview of the present knowledge of neutrino masses and mixing, we summarize what can be learned about physics beyond the standard model from the various proposed ne…
Seesaw-constrained MSSM, Solution to the SUSY CP Problem and a Supersymmetric Explanation of
K. S. Babu, B. Dutta, R. N. Mohapatra
We analyze CP violation in the supersymmetric standard model (MSSM) embedded minimally into a left-right symmetric gauge structure with the seesaw mechanism for neutrino masses. Wi…
Up-Down Unification, Neutrino Masses and Rare Lepton Decays
K. S. Babu, B. Dutta, R. N. Mohapatra
In a recent paper, we showed that tree level up-down unification of fermion Yukawa couplings is a natural consequence of a large class of supersymmetric models. They can lead to vi…
