In this work we give a theoretical description of the elastic vector meson production in diffractive DIS developed within the kt-factorization formalism . Since the kt-factorization scheure does not require large values of Q2+mv, we conduct an analysis that is applicable to all values of Q2 from photo- up to highly virtual production of vector mesons . The basic quantity in this approach - the unintegrated gluon structure function - was for the first time extracted from the experimental data an F2p, thoroughly investigated, and consistently used in the vector meson production calculation. Moreover ; by limiting ourselves to the lowest Fock state of the vector meson, we were able to construct in a closed form the theory of spin-angular coupling in the vector meson. This allowed us for the firnt time to address the production of a vector meson in a given spin-angular state . We performed an extensive analytical and numerical investigation of the properties of 1S, 2S, and D-wave vector meson production reactions . Treating the physical ground state vector mesons as purely 1S states, we observed a good overall agreement with all available experimental data an vector meson production. For the excited states, our analysis predicts a picture which is remarkably different from 1S-state, so that such reactions can be regarded as potential sources of new information an the structure of excited states in vector mesons . |
