摘要：
We compute two-point functions of lowest weight operators at the next-to-leading order in the couplings for the beta-deformed N = 4 SU( N) SYM. In particular we focus on the CPO Tr(Phi(2)(1)) and the operator Tr(Phi(1)Phi(2)) not presently listed as BPS. We find that for both operators no anomalous dimension is generated at this order, then confirming the results recently obtained at lowest order in [5]. However, in both cases a finite correction to the two-point function appears.
