Abstract: We report a search for the decays B-> K+ pi- pi- and B-> K- K- pi+, whichare highly suppressed in the Standard Model. Using a sample of 467 +- 5 x10^6 BBbar pairs collected with the BaBar detector, we do not see any evidenceof these decays and determine 90% confidence level upper limits of BFB-> K+pi- pi- < 9.5 x 10^-7 and BFB-> K- K- pi+ < 1.6 x 10^-7 on thecorresponding branching fractions, including systematic uncertainties.
