Abstract

Anomalous dimension of the simplest nontrivial single impurity operator in the β = 1/2 deformed theory is determined at six loops from the AdS/CFT correspondence. Lüscher correction is evaluated at the third nontrivial order in the t'Hooft coupling in terms of multiple zeta values. The result can be simplified into the products of simple zeta functions and the same form of the correction is expected for the Konishi operator at six loops, too.
