Abstract

The local and manifestly covariant Lagrangian interactions in four spacetime dimensions that can be added to a free model that describes a massless Rarita–Schwinger theory and an Abelian BF theory are constructed by means of deforming the solution to the master equation using specific cohomological techniques.
