Study of hadronic five-body decays of charmed mesons
We study the decay of D+ and D+s mesons into charged five-body final states, and report the discovery of the decay mode D+→K+K−π+π+π−, as well as measurements of the decay modes D+→K−π+π+π+π−, Ds+→K+K−π+π+π−, Ds+→φπ+π+π− and D+/Ds+→π+π+π+π−π−. An analysis of the resonant substructure for D+→K−π+π+π+π− and Ds+→K+K−π+π+π− is included, with an indication that both decays proceed primarily through an a1 vector resonance.
