Abstract
We study the decay of Ds+ mesons into final states involving a KS0 and report the discovery of Cabibbo suppressed decay modes Ds+ → K0π−π+π+ (179±36 events) and D+ → K0π+ (113±26 events). The branching fraction ratios for the new modes are Γ (Ds+→KS0π−π+π+) = S s S 0.18±0.04±0.05and Γ(Ds+→KS0π+) =0.104±0.024±0.014.File in questo prodotto:
