Energy dependence of exclusive vector-meson production in ep interactions at HERA
Aharon Levy
Abstract
The energy dependence of exclusive vector meson (V) production is studied using the ZEUS data. The SU(4) universality of V cross sections in the Q2+MV2 scale is tested. The energy dependence of the ratio of the cross sections for V production to the total γ*p cross section is compared with expectations based on pQCD and Regge approaches.
