  "abstract": "Motivated by experimental results on $\\bar B\\to D^{(*)}K^-K^{0}$, we use a factorization approach to study these decays. Two mechanisms concerning kaon pair production arise: current-produced (from vacuum) and transition (from the $B$ meson). The kaon pair in the $\\bar B {}^0\\to D^{(*)+}K^-K^0$ decays can be produced only by the vector current (current-produced), whose matrix element can be extracted from $e^+e^-\\to K\\bar K$ processes via isospin relations. The decay rates obtained this way are in good agreement with experiment. The $B^-\\to D^{(*)0}K^-K^0$ decays involve both current-produced and transition processes. By using QCD counting rules and the measured $B^-\\to D^{(*)0} K^- K^0$ decay rates, the measured decay spectra can be understood.",
