Özet

The anomalous magnetic (ãτ) and electric dipole (d̃τ) moment of tau lepton described in ττ̄γ vertices are studied via μ+μ−→τ+τ− process at the Muon colliders designed with the proposed center-of-mass-energy/integrated luminosity configurations of 3 TeV/ 1 ab−1 and 10 TeV/ 10 ab−1. We obtained the 95% confidence level limits on the ãτ and d̃τ parameters without and with systematic uncertainty of 10% and compared with the experimental results. The most stringent limits on the anomalous couplings without systematic uncertainty are −2.63×10−4<ãτ<2.65×10−4 and ∣d̃τ∣≤1.47×10−18ecm at s=10TeV and Lint= 10 ab−1 option of the Muon collider. Our results show that the Muon colliders lead to a remarkable improvement on the current experimental limits of the anomalous magnetic and electric dipole moments of the tau lepton.
