Measurement of the $B\to \phi\phi K$ branching fraction

We present a preliminary measurement of the branching fraction for charged B-meson decays to the final state $\phi \phi K^+$, with a $\phi\phi$ invariant mass below the $\eta_c$ threshold. We use a dataset of 230 milllion $B\bar{B}$ pairs collected with the BaBar detector operating at the PEP-II asymmetric-energy $e^+e^-$ collider at SLAC.
