نویسنده
چکیده
On behalf on the ZEUS Collaboration The energy dependence of exclusive vector meson (V) production is studied using the ZEUS data. The SU(4) universality of V cross sections in the Q 2 + M 2 V scale is tested. The energy dependence of the ratio of the cross sections for V production to the total γ * p cross section is compared with expectations based on pQCD and Regge approaches.

Recent measurements of diffractive vector-meson production with the general-purpose detectors H1 and ZEUS in electron-proton interactions with 300 GeV center-of-mass energy at the HERA accelerator complex have stimulated great interest in the question of whether perturbative QCD (pQCD) can provide an accurate description of such diffractive processes. The high flux of quasi-real photons from th...

We describe the current status of the diffractive vector meson production calculations within the kt factorization approach. Since the amplitude of the vector meson production off a proton is expressed via the differential gluon structure function (DGSF), we take a closer look at the latter and present results of our new improved determination of the DGSF from the structure function F2p. Having...

The question whether traditional leading twist QCD is the relevant description of HERA small-x data has still no clear-cut answer. A particularly successful saturation model proposed by Golec-Biernat and Wüsthoff (GBW) [1] suggests that the common picture of a proton looking like a dilute set of partons might be unjustified. We have recently shown directly that the proton is a dense system alre...

QED radiative corrections to the cross section of diffractive electro-and photoproduction of vector mesons is calculated at HERA energies. Both semi-analytical and Monte Carlo approaches are discussed and compared.

Measurements of vector mesons at HERA allow a detailed study of diffractive and non-diffractive production mechanisms, fragmentation and decay branching ratios. Results are presented on hadronic resonance measurements. In addition, the first observation of two meson states at masses around 1500 MeV and 1700 MeV are reported using inclusive K 0 s K 0 s production in deep inelastic ep scattering ...
