We report a search for the decay B0→J/ψ, using a sample of 657×106 BB̄ pairs collected with the Belle detector at the Υ(4S) resonance. No statistically significant signal is found and an upper limit for the branching fraction is determined to be B(B0→J/ψ)<9.4×10-7 at 90% confidence level. © 2008 The American Physical Society.
