| The two--jet invariant mass spectrum as measured in the UA2 experiment is used to search for additional heavy vector bosons decaying to two--jets. The mass of an additional W boson that couples to fermions with a V +A form is constrained to be greater than 261 GeV to the 90% confidence level. A limit on the production cross section of additional W and Z bosons is given as a function of the boson mass. A limit on the production of excited quarks is also given as a function of the excited quark mass. 1 Laboratorium fur Hochenergiephysik, Universitat Bern, Sidlerstraße 5, 3012 Bern, Switzerland 2 Cavendish Laboratory, University of Cambridge, CB3 0HE, UK 3 CERN, 1211 Geneva 23, Switzerland 4 Lehrstuhl fur Exp.
