A study of the decay [Formula: see text] is performed using 81 fb -1 of data collected at the ϒ(4 S ) with the BABAR detector at PEP-II. The branching fraction of [Formula: see text] is measured to be (6.7 ± 0.9 ± 0.6) × 10 6 . An upper limit on the branching fraction of [Formula: see text], where Θ* ++ is a narrow state decaying to pK + , is set to be 1.5 × 10 -7 for 1.43 < m(Θ* ++ ) < 1.85 GeV/c 2 at 90% confidence level. All results are preliminary.
