Abstract:

 We present results of searches for technirho, techniomega, and Z'
 particles, using the decay channels technirho, techniomega,
 Z'->e+e-. The search is based on 124.8 pb^-1 of data collected by the
 DZero detector at the Fermilab Tevatron during 1992-1996. In the
 absence of a signal, we set 95% CL upper limits on the cross sections
 for the processes pbarp->technirho, techniomega, Z'->e+e- as a
 function of the mass of the decaying particle. For certain model
 parameters, we exclude the existence of degenerate technirho and
 techniomega states with masses below about 200 GeV. We exclude a Z'
 with mass below 670 GeV, assuming that it has the same couplings to
 fermions as the Z boson.
