Four-dimensional couplings among BF and massless Rarita-Schwinger theories: a BRST cohomological approach

摘要

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.
