Abstract
The structure of the nonperturbative vector meson vertex function complicates the proof of the factorisation theorem for the reaction γ∗p→Vp. It leads to additional contributions but, in a simple model for the vertex function, gauge invariance ensures that they cancel and factorisation is preserved.
