(ΔA_{CP})_{LHCb} and the fourth generation    [PDF]

A. N. Rozanov, M. I. Vysotsky

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.
