Abstract
Using 281 pb(-1) of data collected with the CLEO-c detector at the psi(3770) resonance, we have studied Cabibbo-suppressed decays of D mesons to final states with two kaons. We present results for the absolute branching fractions of the modes D-0 -> K+K-, D-0 -> (KSKS0)-K-0, and D+-> (K+KS0). We measure B(D-0 -> K+K-) = (4.08 +/- 0.08 +/- 0.09) x 10(-3), B(D-0 -> (KSKS0)-K-0) = (1.46 +/- 0.32 +/- 0.09) x 10(-4), and B(D+-> (K+KS0)) = (3.14 +/- 0.09 +/- 0.08) x 10(-3). We also determine the ratio B(D-0 -> K+K-)/B(D-0 -> pi(+)pi(-)) = 2.89 +/- 0.05 +/- 0.06. For each measurement, the first uncertainty is statistical and the second uncertainty is systematic.
