Measurement of indirect CP-violating asymmetries in $D^0\to K^{+}{K}^{-}$ and $D^0\to {\pi }^{+}{\pi }^{-}$ decays at CDF

CDF Collaboration, T. Aaltonen, S. Amerio +399

We report a measurement of the indirect CP-violating asymmetries ($A_{\Gamma }$) between effective lifetimes of anticharm and charm mesons reconstructed in $D^0\to K^{+}{K}^{-}$ and $D^0\to π^+…
