Color Dipole Systematics of the Diffraction Slope in Diffractive Photo- and Electroproduction of Vector Mesons

摘要

We present the first evaluation of the color dipole diffraction slope fromthe data on diffractive photo- and electroproduction of vector mesons. Theenergy and dipole size dependence of the found dipole diffraction slope areconsistent with the color dipole gBFKL dynamics.
