Abstract
Charged hadronic four-body decays of D0 mesons have been studied in the E687 photoproduction experiment at Fermilab. Branching ratios relative to the D0 → K−pi+pi+pi− decay mode for the Cabibbo-suppressed decays D0 → pi−pi+pi−pi+, D0 → K−K+pi−pi+ have been measured and the first evidence of the D0 → K−K+K−pi+ decay mode is reported. An analysis of the D0 → K−K+pi−pi+ resonance structure is also presented.
