We compute two-point functions of lowest weight operators at thenext-to-leading order in the couplings for the beta-deformed N=4 SYM. Inparticular we focus on the CPO Tr(Phi_1^2) and the operator Tr(Phi_1 Phi_2) notpresently listed as BPS. We find that for both operators no anomalous dimensionis generated at this order, then confirming the results recently obtained inhep-th/0506128. However, in both cases a finite correction to the two-pointfunction appears.Comment: LaTex, 9 pages, 4 figures; v2:minor corrections and one reference added; v3: misprint correcte
