Abstract:
LHCb collaboration measured CPV at the level of one percent in
the difference of assymetries in
D0(¯D0)→π+π−,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.
