Single impurity operators at critical wrapping order in the beta-deformed N=4 SYM

arXiv:0811.4594 · doi:10.1088/1126-6708/2009/08/034

Abstract

We study the spectrum of one single magnon in the superconformal beta-deformed N=4 SYM theory in the planar limit. We compute the anomalous dimensions of one-impurity operators O_{1,L}= tr(phi Z^{L-1}), including wrapping contributions at their critical order L.
