We present analytical results both in momentum and position space for the massless correlators of the vector and scalar currents to order {alpha}{sub s}{sup 4} as well as for the tensor currents to order {alpha}{sub s}{sup 3}. The evolution equations for the correlators together with all relevant anomalous dimensions are discussed in detail. As an application we present explicit conversion formulas relating the MS-bar-renormalized vector, scalar and tensor currents to their counterparts renormalized in the X-space renormalization scheme more appropriate for lattice calculations.
