Abstract

We present the results of a search for the production of new particles decaying into two jets in p̅p collisions at √s =1.8 TeV, using the DØ 1992–1995 data set corresponding to 109 pb-1. We exclude at the 95% confidence level the production of excited quarks (q*) with masses below 775 GeV/c2, the most restrictive limit to date. We also exclude standard-model-like W′ (Z′) bosons with masses between 300 and 800 GeV/c2 (400 and 640 GeV/c2). A W8 boson with mass ,786 GeV/c2 has been excluded by previous measurements, and our lower limit is therefore the most stringent to date.
