Abstract

Relying on the collinear factorization approach, we demonstrate that H1 and ZEUS measurements of exclusive light vector meson and photon electroproduction cross sections can be simultaneously described for photon virtualities of Q >2 GeV. Our findings reveal that quark exchanges are important in this small xBj region and that in leading order approximation the gluonic skewness ratio is much smaller than one.
