BRST-co-BRST Quantization of Reparametrization Invariant Theories
Geza Fulop
Abstract
We study some reparametrization invariant theories in context of the BRST-co-BRST quantization method. The method imposes restrictions on the possible gauge fixing conditions and leads to well defined inner product states through a gauge regularisation procedure. Two explicit examples are also treated in detail.
