Abstract
We present the results of a search for the production of new particles decaying into two jets in p-bar p collisions at s√=1.8TeV, using the DØ 1992–1995 data set corresponding to 109pb(-1). We exclude at the 95% confidence level the production of excited quarks (q*) with masses below 775 GeV/c(2), the most restrictive limit to date. We also exclude standard-model-like W′ (Z′) bosons with masses between 300 and 800 GeV/c(2) (400 and 640 GeV/c(2)). A W′ boson with mass <786GeV/c(2) has been excluded by previous measurements, and our lower limit is therefore the most stringent to date.
