Asymptotic Conformal Invariance in a Non-Abelian Chern-Simons-Matter Model | J. L. Acebal
; | Date: |
17 Dec 2001 | Journal: | Phys.Lett. B528 (2002) 163-168 | Subject: | hep-th | Abstract: | One shows here the existence of solutions to the Callan-Symanzik equation for the non-Abelian SU(2) Chern-Simons-matter model which exhibits asymptotic conformal invariance to every order in perturbative theory. The conformal symmetry in the classical domain is shown to hold by means of a local criteria based on the trace of the energy-momentum tensor. By using the recently exhibited regimes for the dependence between the several couplings in which the set of $eta$-functions vanish, the asymptotic conformal invariance of the model appears to be valid in the quantum domain. By considering the SU(n) case the possible non validity of the proof for a particular n would be merely accidental. | Source: | arXiv, hep-th/0112149 | Services: | Forum | Review | PDF | Favorites |
