Özet

© 2021The potential of the process γγ→ττ¯γ is examined in a model-independent way using the effective Lagrangian approach for the International Linear Collider, a proposed electron-positron machine which is designed with standard configurations of 0.25 TeV/2000 fb−1, 0.35 TeV/200 fb−1 and 0.5 TeV/4000 fb−1. The limits obtained for the tau lepton's anomalous magnetic dipole moment a˜τ and the tau lepton's anomalous electric dipole moment d˜τ defining the anomalous ττ¯γ couplings at 95% confidence level and systematic uncertainties of δsys=0,5,10% are compared with the experimental results. The best limits obtained with δsys=0% on the anomalous couplings are −0.00082
