BRST approach to Lagrangian formulation of bosonic totally antisymmeric tensor fields in curved space

Understand

We apply the BRST approach, previously developed for higher spin field theories, to gauge invariant Lagrangian construction for antisymmetric massive and massless bosonic fields in arbitrary d-dimensional curved space.

• The obtained theories are reducible gauge models both in massless and massive cases and the order of reducibility grows with the value of the rank of the antisymmetric field.
• In both the cases the Lagrangians contain the sets of auxiliary fields and possess more rich gauge symmetry in comparison with standard Lagrangian formulation for the antisymmetric fields.
• This serves additional demonstration of universality of the BRST approach for Lagrangian constructions in various field models.
