$CP$-violating asymmetries from the decay-time distribution of prompt $D^0 \to K^+ K^-$ and $D^0 \to \pi^+\pi^-$ decays in the full $\mbox{LHCb}$ Run 1 data sample. Measurement using unbinned, acceptance corrected decay-time.

A study of indirect $CP$ violation in $D^0$ mesons is presented through a measurement of the asymmetry of the effective decay widths of $D^0$ and $\overline{D}^0$ mesons to $CP$ eigenstates. This observable, known as $A_{\Gamma}$, is measured with the $CP$ eigenstates $K^+ K^-$ and $\pi^+ \pi^-$ usi...
