Charmed penguin versus BAU
  Since the Standard Model most probably cannot explain the large value of CP
asymmetries recently observed in D-meson decays we propose the fourth
quark-lepton generation explanation of it. As a byproduct weakly mixed leptons
of the fourth generation make it possible to save the baryon number of the
Universe from erasure by sphalerons. An impact of the 4th generation on BBN is
briefly discussed.
