Abstract

We report evidence for the decay mode

B \to ϕ ϕ K

based on an analysis of

78 {f b}^{- 1}

of data collected with the Belle detector at KEKB. This is the first example of a

b \to s \bar{s} s \bar{s} s

transition. The branching fraction for this decay is measured to be

B (B^{\pm} \to ϕ ϕ K^{\pm}) = ({2.6}_{- 0.9}^{+ 1.1} \pm 0.3) \times 10^{- 6}

for a

ϕ ϕ

invariant mass below

2.85 G e V / c^{2}

. Results for other related charmonium decay modes are also reported.
