Sensitivity on the Dipole Moments of the 𝜏-Neutrino at 𝑒⁺𝑒⁻ Colliders: ILC and CLIC

Figure 1

The Feynman diagrams contributing to the process 𝑒⁺𝑒⁻→𝜈𝜈𝛾 (1, 2) when the 𝑍 vector boson is produced on mass-shell and (3, 4) contributions from anomalous neutrino electromagnetic couplings with initial-state radiation.
