Precise measurement of CP violating τ EDM through e + e − → γ *, ψ(2s) → τ + τ −
Abstract A nonzero electric dipole moment of a tauon, d τ , signals CP violation and provides an important probe for new physics. We study methods to measure d τ at low energy e + e − colliders through the processes e + e − → γ *, ψ(2S) → τ + τ − with τ ± decays into a charged hadron and a tau neutr...
