Abstract

In a class of Es inspired models with a light additional neutral vector boson, we discuss the effects of the magnetic moment of the tau neutrino by analyzing e(+)e(-) --> <nu(nu )over bar> at the Z-pole. We take into account present scenarios for the extra Abelian group and vary extra neutral gauge boson mass beyond the present experimental exclusion limits. The present LEP experimental results prove that we can set an upper bound on the magnetic moment of the tan neutrino: K-nuT less than or equal to 1.83 x 10(-6).
