Contribution to the study of matter-antimatter cosmological models
Abstract
The hypothesis of matter-antimatter symmetry in the universe is examined, and it is concluded that the mechanisms proposed so far for the formation of such a universe are excluded by constraints associated with limits on black hole distortion, deuterium abundance, helium-3 abundance, and cosmic ray flux. The possibility is considered that more efficient mechanisms such as coalescence might satisfy the stringent conditions; the conditions might also be satisfied if the annihilation energy were utilized in an efficient manner. The analysis is concerned with mechanisms for separating nucleons and antinucleons by thermal radiation and with the hydrodynamics of a matter-antimatter emulsion. Other topics briefly discussed include radiative and plasma eras, the quantity of matter in the universe, and the abundance of light elements.
