Search for the decay B+→K0sK0sπ+

We search for charmless decays of charged B mesons to the three-body final state K 0 s K 0 s πr + . Using a data sample of 423.7 fb -1 collected at the Y(4S) resonance with the BABAR detector, corresponding to (465.1 ± 5.1) X 10 6 BB pairs, we find no significant signal and determine a 90% confidence level upper limit on the branching fraction of 5.1 × 10 -7 .
