The BFT Method With Chain Structure
arXiv:hep-th/0311131 · doi:10.1016/j.physletb.2004.01.047
Abstract
We have constructed a modified BFT method that preserves the chain structure of constraints. This method has two advantages: first, it leads to less number of primary constraints such that the remaining constraints emerge automatically; and second, it gives less number of independent gauge parameters. We have applied the method for bosonized chiral Schwiger model. We have constructed a gauge invariant embedded Lagrangian for this model.
