Search for $B^0 \to J/ψϕ$

Abstract

We report a search for the decay $B^0 \to J/ψϕ$, using a sample of 657 $\times 10^6$ $B\bar{B}$ 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 $\mathcal{B}(B^0 \to J/ψϕ) < 9.4 \times 10^{-7}$ at 90% confidence level.
