η, η' distribution amplitudes and form factors in QCD — Shahin Agaev1, Vladimir Braun2, •Nils Offen2, Florian Porkert2, and Andras Schäfer2 — 1Baku State University — 2University of Regensburg
We calculated mass and anomaly corrections to the η and η' distribution amplitudes. These results are used to calculate the η, η' to γγ* form factors at next to leading order including singlett contributions. Issues of factorisation including mass corrections will be discussed as well as experimental data.
