Phenomenological model for electric dipole and magnetic moment experiments

Relaxing P- and T- reversal symmetries is typically captured by adding electric dipole moment (EDM) and new interaction terms to phenomenological models. We argue that removing symmetry constraints might lead to more physical effects compared to what is currently included into conventional phenomenology. In several recent studies we developed the new phenomenological model which includes new pseudoscalar corrections. It can potentially help in matching QFT predictions with high precision measurements of electric and magnetic moments. Considering the EDM and AMM problems in the single framework, our approach could explain why the electric moment continues to escape detection while the gaps between experimental and theoretical predictions of magnetic anomaly emerge.
