Nonuniversality of indirect CP asymmetries in $D\to \pi \pi ,KK$ decays

Amol Dighe, Diptimoy Ghosh, Bhavik P. Kodrani

We point out that, if the direct CP asymmetries in the $D\to {\pi }^{+}{\pi }^{-}$ and $D\to K^{+}{K}^{-}$ decays are unequal, the indirect CP asymmetries as measured in these modes are necessaril…
