Abstract

Description

We present preliminary results of a search for B0-->K0-anti-K0 decays in the K0SK0S final state using a sample of approximately 23 million B-anti-B pairs collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. We find no evidence for a signal and set an upper limit on the branching fraction of 7.3 x 10^{-6} at the 90% confidence level.
