We study quantum Chern-Simons theory as the large-mass limit of the limit D --> 3 of dimensionally regularized topologically massive Yang-Mills theory. This approach can also be interpreted as a BRS-invariant hybrid regularization of Chern-Simo[...]texto impreso
We compute the beta function at one loop for Yang-Mills theory using as regulator the combination of higher covariant derivatives and Pauli-Villars determinants proposed by Faddeev and Slavnov. This regularization prescription has the appealing [...]texto impreso
We explicitly show that the Landau gauge supersymmetry of Chem-Simons theory does not have any physical significance. In fact, the difference between an effective action that is both Becchi-Rouet-Stora (BRS) invariant and Landau supersymmetric a[...]texto impreso
We consider a family of local BRS-invariant higher covariant derivative regularizations of SU(N) Chem-Simons theory that do not shift the value of the Chem-Simons parameter k to k + sign(k) c(v) at one loop.texto impreso
We regularize QCD using the combination of higher covariant derivatives and Pauli-Villars determinants proposed by Slavnov. It is known that for pure Yang-Mills theory the Pauli-Villars determinants generate unphysical logarithmic radiative corr[...]
