Production of charged scalar particles with well defined angular momentum in de Sitter spacetime
Abstract
We study the production of charged scalar particles with well defined angular momentum, in the presence of an external Coulomb field on de Sitter expanding universe. This process of particle production is studied as a perturbative phenomenon applying the theory of quantum electrodynamics on de Sitter spacetime developed in \cite{1}-\cite{3}. The probability of particle production is computed and our results show the dependence of the probability in terms of the orbital quantum number. Our graphical results show that, the most probable transitions are those that generate particles with small angular momentum. Is obtained also that the momentum is not conserved and that the probability of particle production is significative for large values of the Hubble's constant, corresponding to the early universe.
