초록

We study the decay of D-s(+) mesons into final states involving a K-S(0) and report the discovery of Cabibbo suppressed decay modes D-s(+) --> K-S(0)pi(-)pi(+)pi(+) (179+/-36 events) and D-s(+) --> K-S(0)pi(+) (113+/-26 events). The branching fraction ratios for the new modes are Gamma(D-s(+) --> K-S(0)pi(-)pi(+)pi(+)) / Gamma(D-s(+) --> K-S(0)pi(-)pi(+)pi(+)) = 0.18+/-0.04+/-0.05 and Gamma(D-s(+) --> K-S(0)pi(+)) / Gamma(D-s(+) --> K-S(0)pi(+)) = 0.104+/-0.024+/-0.014.
