Abstract

LHCb has collected the world's largest sample of charmed hadrons. This sample is used to measure the mixing parameters in the $D^0$-$\bar{D}^0$ system and to search for indirect $CP$ violation. This contribution focuses on measurements of $A_{\Gamma}$ with $D^*$ and semileptonic $B$ decays and on mixing measurements and a search for $CP$ violation in $D\to K\pi$ decays.
