# Interaction of massless minimally coupled scalar field with spinor field in de Sitter universe

@article{Ahmadi2020InteractionOM, title={Interaction of massless minimally coupled scalar field with spinor field in de Sitter universe}, author={Y. Ahmadi}, journal={International Journal of Modern Physics D}, year={2020} }

The interaction of massless minimally coupled scalar field and spinor field (Ψ + Φm → Ψ + Φm) is investigated and the behavior of interaction and scattering matrix in Minkowski limit is studied. It is seen that the massless minimally coupled scalar field operator, the interaction Lagrangian and the scattering matrix become zero. Also the incoming and outgoing spinor fields, which in de Sitter space-time are different and are interacted with massless minimally coupled scalar field, in null…
