# Super-gauge field in de Sitter universe

@article{Parsamehr2015SupergaugeFI, title={Super-gauge field in de Sitter universe}, author={Sajad Parsamehr and Mohammad Enayati and M. V. Takook}, journal={The European Physical Journal C}, year={2015}, volume={76}, pages={1-13} }

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…
