Energy and Q(2) dependence of elastic vectormeson production and the proton structure function F-2

In the framework of the Model of the Stochastic Vacuum elastic hadron-hadro n scattering, photo- and electroproduction of vectormesons and also F-2(Q(2 )) can be well described at center of mass energy approximately 20 GeV. The scattering amplitude is derived by smearing the color dipole-dipole scatte ring, which is calculated nonperturbatively in the Model of the Stochastic Vacuum, with appropriate wavefunctions. For the considered processes the di poles have extensions in the range of hadron sizes. We now extend this idea to small dipoles and high energies. The energy dependence is modeled in a phenomenological way: we assume that there a two pomerons, the soft- and th e hard-pomeron, each being a simple pole in the complex angular plane. We c ouple dipoles of hadronic size to the soft-pomeron and small dipoles to the hard-pomeron. For small dipoles we take the perturbative gluon exchange in to account. By that way we obtain an energy dependent dipole-dipole scatter ing amplitude which can be used for all the processes with the same paramet ers. We show that this approach can describe in addition to all the low ene rgy results (20 GeV) also the HERA data for the considered processes in a l arge energy and Q(2) range. Especially the right. transition from the soft to the hard behavior is observed.
