Abstract
Using 281pb-1 of data collected with the CLEO-c detector at the ψ(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 D0→K+K-, D0→KS0KS0, and D+→K+KS0. We measure B(D0→K+K-)=(4.08±0.08±0.09)×10-3, B(D0→KS0KS0)=(1. 46±0.32±0.09)×10-4, and B(D+→K+KS0)=(3.14±0. 09±0.08)×10-3. We also determine the ratio B(D0→K+K-)/ B(D0→π+π-)=2.89±0.05±0.06. For each measurement, the first uncertainty is statistical and the second uncertainty is systematic.
