Study of the decay mode D^0 -> K-K+pi-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 $D^0\to K^{-}{K}^{+}{\pi }^{-}{\pi }^{+}$. From a sample of $2669\pm 101$ fully reconstructed $D^0\to K^{-}{K}^{+}{\pi }^{-}{\pi }^{+}$ events, we measure $\Gamma (D^0\to K^{-}{K}^{+}{\pi }^{-}{\pi }^{+})/\Gamma (D^0\to K^{-}{\pi }^{-}{\pi }^{+}{\pi }^{+})=0.0295\pm 0.0011(stat.)\pm 0.0008(syst.)$. A coherent amplitude analysis has been performed to determine the resonant substructure of this decay mode. This analysis reveals a dominant contribution from $D^0\to K_1^{+}K-$ modes.
