Lifetime differences, direct CP violation, and partial widths in D-0 meson decays to K+K- and pi(+)pi(-) Academic Article uri icon

abstract

  • We describe several measurements using the decays (Formula presented) and (Formula presented) We find the ratio of partial widths, (Formula presented) to be (Formula presented) where the first error is statistical and the second is systematic. We observe no evidence for direct (Formula presented) violation, obtaining (Formula presented) and (Formula presented) In the limit of no (Formula presented) violation we measure the mixing parameter (Formula presented) by measuring the lifetime difference between (Formula presented) or (Formula presented) and the (Formula presented) neutral state, (Formula presented) We see no evidence for mixing. 2002 The American Physical Society.
