Abstract: (arXiv)
We report a search for the decay B0J/ψϕB^0 \to J/\psi \phi, using a sample of 657 ×106\times 10^6 BBˉB\bar{B} pairs collected with the Belle detector at the Υ(4S)\Upsilon(4S) resonance. No statistically significant signal is found and an upper limit for the branching fraction is determined to be B(B0J/ψϕ)<9.4×107\mathcal{B}(B^0 \to J/\psi \phi) < 9.4 \times 10^{-7} at 90% confidence level.
