Resumen:
|
We consider a biparametric family of BRS invariant regularization methods of SU (N) Chem-Simons theory (the parameters defining the family taking arbitrary values in R2) and show that the one-loop shift k --> k + sign(k) N of the Chern-Simons parameter k occurs for arbitrary values of the family defining parameters. This strongly supports the conjecture that the shift of k is universal for BRS invariant regulators
