Fermion asymmetry of the Universe and the W condensate

Possible appearance of a homogeneous condensate of charged W bosons in the quark-lepton matter is investigated in framework of various field models. It is shown for the Weinberg-Salam model, that at ratios of the baryonic charge to the leptonic charge in the matter, satisfying the inequality B/L > 4/3, and at some fermion density, the appearance of the W- condensate is preferable from the energetic point of view, while at the inverse condition B/L < 4/3 the W+ condensate is preferable. In the limit of super-high densities the appearance of the W condensate results in the levelling of the partial densities of various kinds of leptons and quarks
