(\Delta A_{CP})_{LHCb} and the fourth generation

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.
