The results from a search for the flavor-changing neutral current decays were presented. The data sample was collected with the BABAR detector at PEP-II B factory. The signal efficiency of the decays were determined from phase-space Monte Carlo simulations. The Bele central value of 90% C.L. was obtained and was found close to standard model predictions for these branching fractions.
