We present a search for the pair-production of a heavy colored
particle $Y$ which decays to a pair of quarks or gluons, leading to
a final state with four hadronic jets. We consider both non-resonant
production via an intermediate gluon as well as resonant production
via a heavy intermediate colored particle $X$. We use data collected
by the CDFII experiment in $p\bar{p}$ collisions at $s**(1/2)=1.96$
TeV corresponding to integrated luminosity of 6.6 fb${-1}$. We find
the data to be consistent with standard model predictions. We report
limits on $\sigma(p\bar{p}--> YY --> jjjj)$ versus $m_Y$ and
$\sigma(p\bar{p}--> X--> YY --> jjjj)$ versus $m_X$ and
$m_Y$. The results are translated into upper limits on the cross
sections for new physics in several resonant and non-resonant processes.
