Abstract

Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement for the Cabibbo-suppressed decay mode D-0 -> K(+)K(-)pi(+)pi(-). We measure: Gamma(D-0 -> K(+)K(-)pi(+)pi(-))/Gamma(D-0 -> K(-)pi(-)pi(+)pi(+)) = 0.0295 +/- 0.0011 +/- 0.0008. An amplitude analysis has been performed in order to determine the resonant substructure of this decay mode. The dominant components are the decays D-0 -> K-1(1270)K-+(-), D-0 -> K-1(1400)K-+(-) and D-0 -> p(770)(0)phi(1020).
