FALAHI, S.  y  PARSAMEHR, S.. Conjugate spinor field equation for massless spin- 3/2 field in de Sitter ambient space. Rev. mex. fis. [online]. 2021, vol.67, n.3, pp.465-470.  Epub 21-Feb-2022. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.67.465.

The quantum field theory in de Sitter ambient space provides us with a comprehensive description of massless gravitational fields. Using the gauge-covariant derivative in the de Sitter ambient space, the gauge invariant Lagrangian density has been found. In this paper, the equation of the conjugate spinor for massless spin-3/2 field is obtained using the Euler-Lagrange equation. Then the field equation is written in terms of the Casimir operator of the de Sitter group. Finally, the gauge invariant field equation is presented.
