LHCb collaboration measured CPV at the level of one percent in the difference of assymetries in $D^0(\bar D^0)\to \pi^+ \pi^-, K^+ K^-$ decays. If confirmed on a larger statistics and final systematics this would mean New Physics manifestation. The fourth quark-lepton generation can be responsible for the observed effect.
