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

Abstract

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.
