Charge asymmetry of new stable quarks in baryon asymmetrical Universe
  Effects of electroweak phase transition (EWPT) in balance between baryon
excess and the excess of stable quarks of new generation is studied. With the
conservation of SU(2) symmetry and other quantum numbers, it makes possible
sphaleron transitions between baryons, leptons and new of leptons and quarks. A
definite relationship between the excess relative to baryon asymmetry is
established. In passing by we also show the small, yet negligible dilution in
the pre-existing dark matter density due the sphaleron transition.
