We search for the factorization-suppressed decays B→χc0K(*) and B→χc2K(*), with χc0 and χc2 decaying into J/ψγ, using a sample of 124×106 BB̄ events collected with the BABAR detector at the PEP-II storage ring of the Stanford Linear Accelerator Center. We find no significant signal and set upper bounds for the branching fractions.
