New Vector Field and BRST Charges in 2-form Einstein Gravity
arXiv:hep-th/9302004 · doi:10.1016/0370-2693(93)91185-P
Abstract
A new vector field is introduced into 2-form Einstein gravity in four dimensions to restore a large symmetry of its topological version. Two different expressions for the BRST charge are given in the system: one of them associated with a set of irreducible symmetries and the other with a set of on-shell reducible symmetries.
