Crucean Cosmin
TL;DR
This paper investigates Coulomb scattering of a charged scalar field in de Sitter spacetime, revealing that unlike in Minkowski space, the momentum modulus is not conserved during scattering.
Contribution
It provides a detailed analysis of Coulomb scattering in de Sitter space, highlighting the non-conservation of momentum modulus, which is a novel insight compared to flat spacetime.
Findings
Momentum modulus is not conserved in de Sitter scattering.
Differences between de Sitter and Minkowski scattering processes.
Solutions of Klein-Gordon equation with definite momentum used for analysis.
Abstract
The scattering of a charged scalar field on Coulomb potential is studied using solutions of the Klein-Gordon equation which have a definite momentum. One obtains that in contrast with what happens on Minkowski case the modulus of momentum is not conserved in the scattering process on de Sitter space.
