Abstract
The results of evaluating the leading-order a,corrections to the correlatio n function for tensor currents in pure gluodynamics are presented. These co rrections to the parton result for the correlation function are not large n umerically, which allows one to use perturbation theory to analyze the reso nance spectrum within the sum-rule method.
