CP violation in the decay Z0 → τ+τ-
Abstract
The search for CP violation in the production of τ pairs on the Z0 peak is discussed. A new limit of 6.7 × 10 -18e cm at 95 % c.l. on the real part of the weak dipole moment of the τ lepton is given. A limit on the imaginary part is presented for the first time: |Im( d∼ τ)| < 4.5 × 10 -17e cm at 95 % c.l..
