Abstract
Charged hadronic five-body decays of D+ and Ds+ mesons have been studied in the E687 photoproduction experiment at Fermilab. We report the first compelling evidence of the decay mode D+, Ds+ → pi−pi−pi+pi+pi+ and the measurements of the decays D+ → K−pi−pi+pi+pi+, Ds+ → K−K+pi−pi+pi+ and Ds+ → phi pi−pi+pi+. An analysis of the D+ → K−pi−pi+pi+pi+ resonance structure is also presented
