Shift versus no-shift in local regularizations of Chern-Simons theory
G. Giavarini, C. P. Martin, F. Ruiz Ruiz
Abstract
We consider a family of local BRS-invariant higher covariant derivative regularizations of SU(N) Chern-Simons theory that do not shift the value of the Chern-Simons parameter k to k+\, sign(k)\, at one loop.
