We present the first model independent search for thre+
e-jet hadronic resonances within multijet events in s**(1/2) ñ.96 TeV p
anti-p collisions at the Fermilab Tevatron using the CDF II detector.
Pair production of supersymmetric gluinos and sqarks with hadronic
R-parity violating decays is employed as an example of a new physics
benchmark for this signature. Selection criteria based on the kinematic
properties of an ensemble of jet combinations within each event help to
extract signal from copi+ous QCD background. Our background estimates
include all-hadronic tt-bar decays that have a signature similar to
the signal. No significant excess outside the top quark mass window is
observed in data with an integrated luminosity of 3.2 fb-1. We place 95%
confidence level limits on the production cross section sigma(p anti-p
--> XX') x BR(gg --> 3 jet + 3 jet) where X, X' ÿ, q, or q, with
q, q --> g + jet, as a function of gluino mass, in the range of 77
GeV/c2 to 240 GeV/c2.
