Fermion pair generation in isotropic cosmology

  • S. G. Mamaev


The generation of particles with a spin of 1/2 in a nonstationary gravitational field corresponding to the quasi-Euclidian Friedman model is considered. Particle generation probability and particle density are evaluated for both the present epoch and near the cosmological singularity. It is shown that the effect is most significant at t ∼ m−1, where m is the particle mass.
