Measurement of D(0)-(D)over-bar(0) mixing using the ratio of lifetimes for the decays D(0)-> K(-)pi(+), K(-)K(+), and pi(-)pi(+)

We present a measurement of D0-D̄0 mixing parameters using the ratios of lifetimes extracted from a sample of D0 mesons produced through the process D*+→D0π+, which decay to K-π+, K-K+, or π-π+. The lifetimes of the CP-even, Cabibbo-suppressed modes K-K+ and π-π+ are compared with that of the CP-mix...
