Abstract

We study bottom flavor abundance in the early Universe near to a temperature TH ' 150 MeV, the condition for hadronization of deconfined quark-gluon plasma (QGP). We show bottom flavor abundance nonequilibrium lasting microseconds. In our study we use that in both QGP, and the hadronic gas phase (HG) b and ¯b quarks near TH are bound in B-mesons and antimesons subject to CP violating weak decays. A coincident non-equilibrium abundance of bottom flavor can lead to matter genesis at required strength: a) The specific thermal yield per entropy is nthb /σ = 1010 ∼ 1013. b) Considering time scales, millions of cycles of B-meson decays, and b¯b-pair recreation processes occur.
