Light new particles generate asymmetries in e+e- to tau+tau- that allow model-dependent constraints on tau dipole moments, including non-zero effects without electron polarization via imaginary parts.
This work provides a comprehensive analysis of light new physics contributions to tau lepton dipole moments, detailing interpretations of asymmetry measurements for spin-0 and spin-1 bosons, their decoupling to the EFT limit, and a case study of a tauphilic vector boson at Belle II.
Introduces an EFT framework relating paramagnetic molecular EDMs to nucleon EDMs, computes the required nuclear matrix elements for BaF via shell model, and derives limits on nucleon EDMs from existing data.
In the B-LSSM the traditional mu-term dominates d_mu and d_tau while B-LSSM-specific CPV parameters also contribute, placing d_mu inside projected Phase-II sensitivity over substantial parameter space and allowing |d_tau| up to 10^{-21} e cm.

The Muon and Tau Electric Dipole Moments in the B-L Supersymmetric Standard Model
In the B-LSSM the traditional mu-term dominates d_mu and d_tau while B-LSSM-specific CPV parameters also contribute, placing d_mu inside projected Phase-II sensitivity over substantial parameter space and allowing |d_tau| up to 10^{-21} e cm.
