Description
We set limits on the magnetic moment and charge radius of the τ neutrino by examining the contributions to the process e+e- → νanti νγ due to such interactions. We find that κ(ντ) < 4x10-6 (i.e. μ(ντ) < 4x10-6 μB, μB = e/2me) and < 2x10-31 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. (orig.)
