Search for new particles decaying to dijets at CDF

Abstract

We have used 106 pb${}^{\ensuremath{-}1}$ of data collected with the Collider Detector at Fermilab to search for new particles decaying to dijets. We exclude at the 95% confidence level models containing the following new particles: axigluons and flavor universal colorons with a mass between 200 and 980 GeV/${c}^{2}$, excited quarks with a mass between 80 and 570 GeV/${c}^{2}$ and between 580 and 760 GeV/${c}^{2}$, color octet techni-$\ensuremath{\rho}$'s with a mass between 260 and 480 GeV/${c}^{2}$, ${W}^{\ensuremath{'}}$ bosons with a mass between 300 and 420 GeV/${c}^{2}$, and ${E}_{6}$ diquarks with a mass between 290 and 420 GeV/${c}^{2}$.
