Effective Lepton Flavor Violating couplings at Muon Collider

We estimate the sensitivity of Wilson coefficients of the lepton flavor-violating dimension-six operators at the proposed ${\mu }^{+}{\mu }^{-}$ collider. We compute the signal significance at $\sqrt{s}$ = 3 and 10 TeV, respectively, with an integrated luminosity of 1 and 10 ab${}^{-1}$ corresponding to unpolarized and polarized initial muon beams. Using the optimal observable method for the kinematic distributions, we study the measurement errors of the effective couplings at the 1-sigma level.
