Vector meson leptoproduction and nonperturbative gluon fluctuations in QCD
- Institut fuer Theoretische Physik der Universitaet Heidelberg, Philosophenweg 16 19, D69120 Heidelberg (Germany)
We present a nonperturbative QCD calculation of diffractive vector meson production in virtual photon nucleon scattering at high energy. We use the nonperturbative model of the stochastic QCD vacuum which yields linear confinement and makes specific predictions for the dependence of high-energy scattering cross sections on the hadron size. Using light cone wave functions of the photon and vector mesons, we calculate electroproduction cross sections for {rho}, {omega}, {phi}, and J/{psi}. We emphasize the behavior of specific observables such as the ratio of longitudinal to transverse production cross section and the t dependence of the differential cross section. {copyright} {ital 1997} {ital The American Physical Society}
