Abstract
In general E-6 inspired model which has two additional U(1) symmetries at t he string scale whose one combination is a light enough vector boson Z(thet a), we compute the contribution of Z(theta) to the gammae(-) --> e(-)<(<nu> )over bar>nu scattering at the aim of calculating the energy loss. We find that the two U(1)'s must be combined at 90 degrees to have a significant co ntribution.
