Cubic Interaction Vertex of Higher-Spin Fields with External Constant Electromagnetic Field
Abstract:
We review an application of BRST construction to deriving the Lagrangian formulation for higher spin field theories. Bosonic and fermionic, massless and massive higher spin field models in flat and AdS spaces are considered including the models with mixed index symmetry. Unconstrained formulation is discussed, the model of totally antisymmetric fermionic
field is constrained, approach to interacting higher spin field theories is developed.
