Spectral moments of two-point correlators in perturbation theory and beyond

S. Groote, J. G. Körner, A. A. Pivovarov

We discuss the choice of weight functions for the moments of the spectral density for two-point correlators of hadronic currents over a finite energy interval. Of phenomenological…
