Bounding the Tau Neutrino Magnetic Moment from Single Photon Searches at LEP

We show that single photon searches at LEP constrain the tau neutrino magnetic moment to be less than $\mathcal{O}({10}^{-6}){\mu }_B$. This bound is competitive with low energy ($s\simeq (30GeV{)}^2$) single photon searches.
