Integral representation of the Feynman propagators of the Dirac fermions on the de Sitter expanding universe
Abstract The propagators of the Dirac fermions on the expanding portion of the $$(1+3)$$ (1+3) -dimensional de Sitter spacetime are considered as mode sums in momentum representation with a fixed vacuum of Bunch–Davies type. The principal result reported here is a new integral representation of the...
