Selected topics in e^+e^- collisions

Abstract

Content : 1) The leading twist pion wave function, 2) "Improved" QCD sum rules with non-local condensates, 3) Pion and kaon form factors and charmonium decays: theory vs experiment, 4) γ^{*}γπ^{o} - form factor, 5) The new non-local axial anomaly, 6) Cross sections γγ--> π^+π^-, K^+K^-, K_S K_S .

Talk given at the International Workshop "e^+e^- collisions from ϕto J/ψ", March 1, 2006, Novosibirsk, Russia; 20 pages, 7 figures; v2: sect.2 expanded to clarify the argumentation, a number of small improvements in the text
