Four-dimensional couplings among BF and matter theories from BRST cohomology

arXiv:hep-th/0310243 · doi:10.1002/andp.200310026

Abstract

The local and manifestly covariant Lagrangian interactions in four spacetime dimensions that can be added to a ``free'' model that describes a generic matter theory and an abelian BF theory are constructed by means of deforming the solution to the master equation on behalf of specific cohomological techniques.
