VECTOR-MESON LEPTOPRODUCTION AND NONPERTURBATIVE GLUON FLUCTUATIONS IN QCD

We present a nonperturbative QCD calculation of diffractive vector mes on production in virtual photon nucleon scattering at high energy. We use the nonperturbative model of the stochastic QCD vacuum which yield s Linear confinement and makes specific predictions for the dependence of high-energy scattering cross sections on the hadron size. Using li ght cone wave functions of the photon and vector mesons, we calculate electroproduction cross sections for rho, omega, phi, and J/psi. We em phasize the behavior of specific observables such as the ratio of long itudinal to transverse production cross section and the t dependence o f the differential cross section.
