Contribution

It provides a statistical framework for understanding antimatter domain formation and derives correlation functions relevant to astrophysical observations.

Findings

Antimatter domains can form in nonhomogeneous baryosynthesis scenarios.

Boundary interactions between matter and antimatter are characterized.

Correlation functions for astrophysical objects and antibaryons are derived.

Abstract

Within the framework of scenarios of nonhomogeneous baryosynthesis, the formation of macroscopic antimatter domains is predicted in a matter-antimatter asymmetrical Universe. The properties of antimatter within the domains are outlined; the matter-antimatter boundary interactions are studied. The correlation functions for two astrophysical objects are calculated. The theoretical expression in the limiting process of the two-points correlation function of an astrophysical object and an antibaryon is derived.
