Abstract
We study the decay of Ds+ mesons into final states involving a KS0 and report the discovery of Cabibbo suppressed decay modes Ds+ → KS0 π- π+ π+ (179 ± 36 events) and Ds+ → KS0 π+ (113 ± 26 events). The branching fraction ratios for the new modes are frac(Γ (Ds+ → KS0 π- π+ π+), Γ (Ds+ → KS0 K- π+ π+)) = 0.18 ± 0.04 ± 0.05 and frac(Γ (Ds+ → KS0 π+), Γ (Ds+ → KS0 K+)) = 0.104 ± 0.024 ± 0.014. © 2008.
