Parity and lepton masses in the left-right symmetric model
Ravi Kuchimanchi
Curiously in the minimal left right symmetric model, chiral symmetry that protects the electron's mass (), due to parity (P), implies in the symmetry limit the vanishing of it…
P and CP solution of the strong CP puzzle
Ravi Kuchimanchi
We use parity (P) to set to zero in the minimal left-right symmetric model with a bi-doublet Higgs, add a heavy vectorlike quark family, and obtain in a novel manner the…
Bayesian probability for leptonic CP phase with strong CP prior
Ravi Kuchimanchi
In a world devoid of axions, the smallness of the strong CP phase can have implications for leptonic CP violation being probed by neutrino experiments. For example, if nature adopt…
Strong CP solution with soft PQ breaking
Ravi Kuchimanchi
A recent work combined the popular left-right parity (LR) and Peccei-Quinn (PQ) symmetries to explain the alignment in quark masses. Since axions may not exist, we break PQ softly…
Scale of left-right symmetry
Ravi Kuchimanchi
Unlike the standard model where neutrino masses can be made arbitrarily small, we find in the minimal left-right symmetric model that Dirac type Yukawa coupling $h_D \sim 10^{-4.2}…
Leptonic CP problem in left-right symmetric model
Ravi Kuchimanchi
We find using the minimal left-right symmetric model that the presence of leptonic CP violation can radiatively generate a strong CP phase at the one-loop level itself, which can b…
Does the hierarchy problem generate the seesaw scale?
Ravi Kuchimanchi
We find that minimizing the number of fine tuning relations in non-supersymmetric models can determine the scales at which some gauge symmetries beyond the standard model must brea…
P stabilizes dark matter and with CP can predict leptonic phases
Ravi Kuchimanchi
We find that spontaneously broken parity (P) or left-right symmetry stabilizes dark matter in a beautiful way. If dark matter has a non-real intrinsic parity \pm i (e.g. Majorana f…
Maximal CP and Bounds on the Neutron Electric Dipole Moment from P and CP Breaking
Ravi Kuchimanchi
We find in theories with spontaneous P and CP violation that symmetries needed to set the tree level strong CP phase to zero can also set all non-zero tree level CP violating phase…
P/CP Conserving CP/P Violation Solves Strong CP Problem
Ravi Kuchimanchi
We find a solution to the Strong CP problem that may be testable at the LHC and future colliders. In this solution CP is broken by parity conserving terms, while parity breaking VE…
Bimaximal Neutrino Mixixing from a Local SU(2) Horizontal Symmetry
R. Kuchimanchi, R. N. Mohapatra
Freedom from global anomalies in the presence of a local SU(2)_H horizontal symmetry under which right handed charged leptons transform nontrivially requires that there be at least…
CP-Like Symmetry, Family Replication, Charge Quantization
Ravi Kuchimanchi
We propose that the physics beyond the standard Weinberg-Salam model is such that matter and the CP conjugate anti-matter fields have the same set of charges with respect to the va…
