Study of hadronic five-body decays of charmed mesons involving KS0
We study the decay of D0 and D+s mesons into five-body final states including a KS0 and report the discovery of the decay mode Ds+→KS0KS0π+π+π−. The branching ratio for the new mode is Γ(Ds+→KS0KS0π+π−π+)Γ(Ds+→KS0K−π+π+)=0.102±0.029±0.029. We also determine the branching ratio of Γ(D0→KS0π+π+π−π−)Γ(D0→KS0π+π−)=0.095±0.005±0.007 as well as an upper limit for Γ(D0→KS0K−π+π+π−)Γ(D0→KS0π+π+π−π−)<0.054 (90% CL). An analysis of the resonant substructure for D0→KS0π+π+π−π− is also performed.
