Abstract: The proof of the fact that there are no nontrivial, consistentcross-couplings that can be added between the Weyl graviton and the masslessRarita-Schwinger field is accomplished by means of a cohomological approach,based on the deformation of the solution to the master equation from theantifield-Becchi-Rouet-Stora-Tyutin BRST formalism. The procedure developedhere relies on the assumptions of locality, smoothness, background Lorentzinvariance, Poincare invariance, and preservation of the number of derivativeswith respect to each field the last hypothesis was made only in antighostnumber zero.
