Measurement of the $CP$ Violation Parameter $\cal{A}_{\Gamma}$ in Two-Body Charm Decays
We present a study of indirect $CP$ violation in $D^0$ mesons through the parameter $\cal{A}_{\Gamma}$. This parameter is defined as the asymmetry of lifetimes measured in decays of $D^0$ and $\bar{D}^0$ mesons to the $CP$ eigenstate $K^{+}K^{-}$. The measurement is performed using absolute lifetime...
