Abstract

Charged hadronic four-body decays of D-0 mesons have been studied in the E687 photoproduction experiment at Fermilab. Branching ratios relative to the D-0 --> K- pi(+)pi(+)pi(-) decay mode for the Cabibbo-suppressed decays D-0 --> pi(-)pi(+)pi(-)pi(+), D-0 --> K(-)K(+)pi(-)pi(+) have been measured and the first evidence of the D-0 --> K(-)K(+)K(-)pi(+) decay mode is reported. An analysis of the D-0 --> K(-)K(+)pi(-)pi(+) resonance structure is also presented.
