EXTENDED BRST RENORMALIZATION

Lavrov P. M.

Information About Author:

The renormalization of general gauge theories curved space-time backgrounds is considered within the Sp(2)-covariant quantization method. It is proven that gauge invariant and diffeomorphism invariant renormalizability to all orders in the loop expansion and the extended BRST symmetry after renormalization is preserved.

Keywords: Extended BRST symmetry, Sp(2) quantization, general covariance, renormalization
