$T^{'}$ Predictions of PMNS and CKM Angles

TL;DR

This paper introduces a $T^{'}$ symmetry-based model that predicts neutrino and quark mixing angles, including CP violation, aligning well with experimental data without extra parameters.

Contribution

The paper extends a previous $T^{'}$ model to include the third quark family and CP violation, providing specific predictions for mixing angles and CP phase.

Findings

Predicted neutrino mixing as tribimaximal.

Quark mixing ratios close to experimental values.

CP violating phase $ heta_{KM} = 65.8^{0}$ within experimental bounds.

Abstract

Generalizing a previous model to accommodate the third quark family and CP violation, we present a $T^{'}$ model which predicts tribimaximal neutrino (PMNS) mixings while the central predictions for quark mixings are $|V_{td}/V_{ts}| = 0.245$ and $|V_{ub}/V_{cb}| = 0.237$ with a predicted CP violating KM phase $\delta_{KM} = 65.8^{0}$. All these are acceptably close to experiment, including the KM phase for which the allowed values are $63^{0} < \delta_{KM} < 72^{0}$, and depend only on use of symmetry $T^{'} \times Z_2$ to define the model and no additional parameters.
