We have used 106 pb(-1) of data collected with the Collider Detector a
t Fermilab to search for new particles decaying to dijets. We exclude
at the 95% confidence level models containing the following new partic
les: axigluons and flavor universal colorons with a mass between 200 a
nd 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-rho's with a ma
ss between 260 and 480 GeV/c(2), W' 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).
