Anomalous processes and leading logarithms

Abstract

Present status of odd-intrinsic sector of low energy QCD is summarized. The two-photon decay of neutral pion is shortly discussed and its connection with the pion decay constant is analysed. A theoretical tool, the leading-log calculation is also presented, its connection with anomalous sector shown and some new results given.
