Abstract

AbstractIn the Affleck–Dine–Linde scenario of baryosynthesis, there exists a possibility of creation of sufficiently large regions with antibaryon excess, which can evolve in antimatter globular clusters only in the result of domain evolution and only at the stage of galaxy formation; their number is demonstrated to increase as a function of time, being determined by the mechanism of antibaryon excess generation and on the properties of the inflaton field and related ones, the Hubble-parameter function at the inflationary stage, as well as the field initial conditions in the Einstein field Equations. Possible discovery of antimatter globular clusters would specify the mechanisms of inflation, baryosynthesis and evolution of antibaryon domains in a baryon-asymmetrical Universe.
