  ABSTRACT: Under some plausible assumptions, we find that the dual formulation of linearized gravity in D=5 can be nontrivially coupled to the topological BF model in such a way that the interacting theory exhibits a deformed gauge algebra and some deformed, on-shell reducibility relations. Moreover, the tensor field with the mixed symmetry (2,1) gains some shift gauge transformations with parameters from the BF sector.

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

  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.

  Conference Proceeding: BF models in dual formulations of linearized gravity

  C. Bizdadea, E. M. Cioroianu, A. Danehkar, M. Iordache, S. O. Saliu, S. C. Sararu
  [show abstract] [hide abstract]
  ABSTRACT: The case of couplings in D = 5 between a simple, maximal BF model and the dual formulation of linearized gravity is considered. All the possible interactions are exhausted by means of computing the "free" local BRST cohomology in ghost number zero.

  Article: An irreducible BRST approach of topological Yang-Mills theory

  C Bizdadea, M Iordache, SO Saliu, EN Timneanu
  [show abstract] [hide abstract]
  ABSTRACT: The topological Yang-Mills theory is quantized in an irreducible manner, at both Lagrangian and Hamiltonian levels. Our procedure resides in replacing the starting reducible generating set, respectively the reducible first-class constraints with some irreducible ones. The ghosts of ghosts will no longer appear. Some cohomological aspects are briefly discussed.
