The Gupta–Bleuler triplet for a vector-spinor gauge field is presented in the de Sitter ambient space formalism. The invariant space of field equation solutions is obtained with respect to an indecomposable representation of the de Sitter group. By using the general solution of the massless spin-$$\frac{3}{2}$$32 field equation, the vector-spinor quantum field operator and its corresponding Fock space is constructed. The quantum field operator can be written in terms of the vector-spinor…

Quantum field theory in the de Sitter universe.

This approach controls the thermal properties and the zero-curvature limit of the fields; it provides a general setting for interacting fields, in which some steps are taken: a Kallen-Lehmann type formula for complete propagators and a treatment of a class of self-energy diagrams and their resummation.
