We present a search for new particles whose decays produce two
jets (dijets) using proton-antiproton collision data corresponding to an
integrated luminosity of 1.13 fb-1 collected with the CDF II detector.
The measured dijet mass spectrum is found to be consistent with
next-to-leading-order perturbative QCD predictions, and no significant
evidence of new particles is found. We set upper limits at the 95%
confidence level on cross sections times the branching fraction for the
production of new particles decaying into dijets with both jets having
a rapi+dity magnitude |y| < 1. These limits are used to determine
the mass exclusions for the excited quark, axigluon, flavor-universal
coloron, E_6 diquark, color-octet techni-rho, W', and Z'.
