Explores q² dependence and imaginary parts of tau g-2 and EDM in SMEFT and 2HDM, proposing methods to measure them at Belle II and STCF to improve a_τ bounds by over an order of magnitude.
Future lepton colliders can improve existing constraints on the tau lepton's dipole moments by several orders of magnitude through complementary channels.
An axion-like particle coupling induces sizable real and imaginary components in the tau EDM, with values potentially accessible at STCF and Belle II.
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.
Anomalous dipole moments of the tau lepton produce measurable effects on tau polarization and spin correlations in gamma-gamma and quark-antiquark induced pair production.
Obtains 95% CL exclusion and 3σ/5σ sensitivity limits on a_τ and d_τ from PbPb collisions at FCC-hh with comparisons to other future colliders.
