A search for the decay B+/- --> K(+/-)K(+/-)pi(-/+) was performed using dat
a collected by the OPAL detector at LEP. These decays are strongly suppress
ed in the Standard Model but could occur with a higher branching ratio in s
upersymmetric models, especially in those with R-parity violating couplings
. No evidence for a signal was observed and a 90% confidence level upper li
mit of 1.29 X 10(-4) was set for the branching ratio. (C) 2000 Published by
