A perturbative production of massive Z bosons and fermion-antifermion pairs from the vacuum in the de Sitter Universe
Diana Dumitrele, Mihaela-Andreea Băloi, Cosmin Crucean
In this paper we study the problem of neutral electro-weak interactions in a de Sitter geometry. We develop the formalism of reduction for the Proca field with the help of the solu…
Z boson emission by a neutrino in de Sitter expanding universe
Mihaela-Andreea Baloi, Cosmin Crucean, Diana Dumitrele
Production of Z bosons in emission processes by neutrinos in the expanding de Sitter universe is studied by using perturbative methods. The total probability and transition rate fo…
Production of charged scalar particles with well defined angular momentum in de Sitter spacetime
Mihaela-Andreea Baloi
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 o…
Annihilation of the scalar pair into a photon on de Sitter spacetime
Mihaela-Andreea Baloi
The annihilation of massive scalar particles in one photon on de Sitter expanding universe is studied, using perturbation theory. The amplitude and probability corresponding to thi…
