TL;DR
This paper reviews mechanisms of baryogenesis, focusing on those that could produce large antimatter regions in the universe, and discusses observational signs of cosmological antimatter.
Contribution
It provides a comprehensive review of baryogenesis models capable of generating antimatter domains and explores their potential observational signatures.
Findings
Certain baryogenesis mechanisms can produce antimatter domains.
Observational evidence for cosmological antimatter is discussed.
Potential signatures include gamma-ray emissions and cosmic ray antimatter.
Abstract
Possible mechanisms of baryogenesis are reviewed. Special attention is payed to those which allow for creation of astronomically significant domains or objects consisting of antimatter. Observational manifestations of cosmological antimatter are discussed.
