Irreducible Hamiltonian approach to the Freedman-Townsend model

TL;DR

This paper derives an irreducible BRST symmetry formulation for the Freedman-Townsend model and compares it with the traditional reducible approach, providing insights into the model's gauge structure.

Contribution

It introduces an irreducible Hamiltonian framework for the Freedman-Townsend model and compares it with the standard reducible method.

Findings

Irreducible BRST symmetry is successfully derived for the model.

Comparison reveals differences and advantages over the reducible approach.

Provides a new perspective on gauge symmetry formulation in the model.

Abstract

The irreducible BRST symmetry for the Freedman-Townsend model is derived. The comparison with the standard reducible approach is also addressed.
