Abstract
We examine the production and decays of extra gauge bosons Z2 and WR in a recently proposed left-right E6 superstring model with alternative assignments of the fermions in the 27 representation of E6. We find that either or decay modes may have a branching fraction as high as 6% and 13%, respectively. The bosonic decays of the Z2 are similar to those found in the minimal rank 5 E6 superstring model, except for a possible new mode. Allowed regions of Z2 mass versus the Z, Z′ mixing are determined from neutral current data.Keywords
