Study of the decay mode D^0 -> K-K-K+pi+

Abstract

Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement of the branching ratio for the Cabibbo-favored decay mode $D^0\to K^{-}{K}^{-}{K}^{+}{\pi }^{+}$. From a sample of $143\pm 19$ fully reconstructed $D^0\to K^{-}{K}^{-}{K}^{+}{\pi }^{+}$ events, we measure $\Gamma (D^0\to K^{-}{K}^{-}{K}^{+}{\pi }^{+})/\Gamma (D^0\to K^{-}{\pi }^{-}{\pi }^{+}{\pi }^{+})=0.00257\pm 0.00034(stat.)\pm 0.00024(syst.)$. A coherent amplitude analysis has been performed to determine the resonant substructure of this decay mode. This analysis reveals a dominant contribution from $\varphi$ and ${\bar{K}}^{\ast 0}(890)$ states.
