Hints on the power corrections from current correlators in x-space

We consider an interpretation of the recent lattice data on the current-cur rent correlators. in the x-space. The data indicate rather striking differe nce between (axial)vector and (pseudo)scalar channels which goes beyond the predictions of the standard non-perturbative models. We argue that if the difference is to be explained by power corrections, there is a unique choic e of the form of the correction. We discuss the emerging picture of the pow er corrections.
