We present an analysis of the recent measurement of eta'-meson production by two virtual photons made by the BaBar collaboration. It is the first measurement of a transition form factor which is entirely within the kinematic regime of the collinear factorization approach, and it thus provides a clean test of the QCD factorization theorem for distribution amplitudes (DAs). We demonstrate that the ...
