Abstract
We report new constraints on the existence of additional Z bosons deri ved from neutrino-electron scattering data. The analysis is based on d ata taken by the CHARM II Collaboration during five years of exposure of the detector to the wide band neutrino beam at CERN. The limits on the mass of these new particles are evaluated in the framework of E6 s uperstring-inspired theories and Left-Right symmetric models. Limits o n the so-called Z1 are also reported.
