A Study of D0 ---> K0(S) K0(S) X decay channels

Journal Article · · Phys.Lett.B
Using data from the FOCUS experiment (FNAL-E831), we report on the decay of D0 mesons into final states containing more than one KS0 . We present evidence for two Cabibbo favored decay modes, D0→KS0KS0K-π+ and D0→KS0KS0K+π- , and measure their combined branching fraction relative to D0→K¯0π+π- to be Γ(D0→KS0KS0K±π∓)Γ(D0→K¯0π+π-)=0.0106±0.0019±0.0010 . Further, we report new measurements of Γ(D0→KS0KS0KS0)Γ(D0→K¯0π+π-)=0.0179±0.0027±0.0026 , Γ(D0→K0K¯0)Γ(D0→K¯0π+π-)=0.0144±0.0032±0.0016 , and Γ(D0→KS0KS0π+π-)Γ(D0→K¯0π+π-)=0.0208±0.0035±0.0021 where the first error is statistical and the second is systematic.
