We have studied the production and corresponding decay signatures of flavor-changing neutral gauge bosons which can arise when E/sub 6/ breaks to give a new low-energy gauge group SU(2)/sub I/ at e/sup +/e/sup -/ and hadron colliders. The non-Hermitian gauge bosons (W/sub I/) in this group couple conventional fermions (e.g., e,d/sup c/) to their exotic partners (E,h/sup c/) in the 27 representation of E/sub 6/. The dominant mechanism for W/sub I/ production in hadron-hadron collisions at the parton level is found to be g+d..-->..W/sub I/+h, which leads to a substantial cross section at both the Superconducting Super Collider and the CERN Large Hadron Collider as well as distinct decay signatures. Pair production of W/sub I/ at high-energy e/sup +/e/sup -/ colliders is found to be sensitive to detailed cancellations between the different amplitudes. Sizable production cross sections of order 1 pb are obtained.
