Can particle production in de Sitter spacetime lead to a matter-dominated universe?, by Bernido, C. C.. International Centre for

Physics

Scientific paper

Using path integrals, it is shown that particle-antiparticle production
in the early univese can lead to an observed matter-antimatter asymmetry
at later times. This result is obtained from an integrability condition
of the Green function for a relativistic scalar particle in de Sitter
spacetime.
