Abstract

We set limits on the magnetic moment and charge radius of the τ neutrino by examining the contributions to the process e⁺e^-→v {Mathematical expression}γ due to such interactions. We find that K(ν_τ)<4×10^-6 (i.e.μ(ν_τ)<4×10^-6μ_B, μ_B=e/2 m_e) and 〈r²〉<2×10^-31 cm² using the combined data of the MAC, ASP, CELLO, and Mark J collaborations for this process. We briefly discuss whether these bounds can be improved in any future e⁺e^- experiments.
