摘要：

Using data taken with the CLEO II detector, we have studied the decays of the D-0 to K+K-, <K-0(K)over bar (0)>, (KSKSKS0)-K-0-K-0, (KSKS0)-K-0 pi(0), K(+)K(-)pi(0). We present significantly improved results for B(D-0-->K+K-) = (0.454 +/- 0.028 +/- 0.035)%, B(D-0 --> <K-0(K)over bar (0)>) = (0.054 +/- 0.012 +/- 0.010)%, and B(D-0 --> (KSKSKS0)-K-0-K-0) = (0.074 +/- 0.010 +/- 0.015)%, where the first errors are statistical and the second errors are the estimate of our systematic uncertainty. We also present a new upper limit B(D-0 --> (KSKS0)-K-0 pi(0)) < 0.059% at the 90% confidence level and the first measurement of B(D-0 --> K(+)K(-)pi(0)) = (0.14 +/- 0.04)%.
