We report the results of a search for the decay B0→K*+K*- with a sample of 454±5 million BB̅ pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at the Stanford Linear Accelerator Center. We obtain an upper limit at the 90% confidence level on the branching fraction for B(B0→K*+K*-)<2.0×10-6, assuming the decay is fully longitudinally polarized.

Abstract

We report the results of a search for the decay B0→K*+K*- with a sample of 454±5 million BB̅ pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at the Stanford Linear Accelerator Center. We obtain an upper limit at the 90% confidence level on the branching fraction for B(B0→K*+K*-)<2.0×10-6, assuming the decay is fully longitudinally polarized.
