Bounding the magnetic and electric dipole moments of tau nu from the process e+e- --> nu bar nu gamma in E6 Superstring Models

A. Gutierrez-Rodriguez, M. A. Hernandez-Ruiz, B. Jayme-Valdes +1

We obtain bounds on the anomalous magnetic and electric dipole moments of the tau-neutrino through the reaction $e^{+}{e}^{-}\to \nu \bar{\nu }\gamma$ at the $Z_1$-pole in the framework of a Lef…
