Renormalization of SUSY Yang-Mills-Chern-Simons in (2+1)D through the Background Field Method

Presented by Mr. Fabricio MARQUES on 24 Jul 2014 from 15:10 to 15:30
Type: Formal SUSY and Strings
Track: Formal SUSY and Strings


The Background Field Method is a quantization procedure which preserves the gauge invariance of a theory in each intermediate step. It was introduced by DeWitt and others for 1-loop calculations. It was then extended for 2-loops by 'tHooft and improved by DeWitt, Boulware and Abbott [1]. In this work the method is applied to quantize the SUSY Yang-Mills-Chern-Simons N=1 model in the absence of matter in (2+1) space-time dimensions. This model was already studied by Ruiz-Ruiz and van Nieuwenhuizen [2] using component fields. Here we use superfields formalism. The divergent supergraphs are classified up to 2-loops using an extended version of A. F. Ferrari's Mathematica package SusyMath [3]. In a next step, matter fields are going to be included as well.
