Description
Assuming a nonvanishing neutrino magnetic moment μ we study τ-neutrino properties in the process e+e-→ν bar νγ from the single photon searches at colliders. We find that for a sufficiently large value of neutrino mass, i.e., m>2.1x(1010μ/μB) MeV (where μB=e/2me is the Bohr magneton), the interference between the diagrams with Z0 and γ exchange becomes important and should be taken into account in future e+e- experiments. Some cosmological and astrophysical implications of this new heavy-neutrino scenario are briefly discussed
