Evidence for B → φφK
Evidence for the charmless three-body decay B→φφK was observed. The branching fraction Β(B±→φφK±) = (2.6-0.9 +1.1±0.3) × 10-6 for Mφφ>2.85 GeV/c2, was measured with a significance of 5.1σ. No signal was observed for the decay B→fJ(2220)K with fJ(2220)→φφ. Significant signals were also observed for B±→ηcK± with ηc→φφ, with ηc → φK+K-, and with ηc→2(K+K-), as well as a signal for B±→J/ψK± with J/ψ→φK+K-.
