We explore QCD calculations for the process where V is a vector meson, in the region and . We compare our calculations for the , and mesons with data from the ZEUS Collaboration at HERA and demonstrate that the BFKL approach is consistent with the data even for light mesons, whereas the two-gluon exchange approach is inadequate. We also predict the differential cross-sections for the and for which no data are currently available.
