Probing the Tau Neutrino Magnetic Moment via the $μ^{-}γ\rightarrow μ^{-}ν\barν$ Process at Future Muon Colliders

We investigate the sensitivity of future muon colliders to the anomalous magnetic moment of the tau neutrino within a model-independent effective field theory framework. The analysis is performed through the subprocess $μ^{-}γ\rightarrow μ^{-}ν\barν$ where the initial-state photon is described using
