The photoproduction of vector mesons
نویسنده
چکیده
At high energy, the photoproduction or electroproduction of Vector Mesons allow to prepare a beam of quark-antiquark pairs of a given flavor. At high momentum transfer, the study of the scattering of these pairs on a nucleon opens up an original window on the quark-gluon structure of hadronic matter, which may eventually shed light on its gluonic content, on correlations between quarks and on the van der Walls part of the interaction between hadrons.

Proton Compton Scattering and Photoproduction of Vector Mesons
Proton Compton scattering and photoproduction of vector mesons at high energies are studied in terms of the quark model. It is shown that under the vector meson dominance hypothesis the quark model gives the rP total hadronic cross section in good agreement with the experimental data. The real-to-imaginary ratio of forward proton Compton scattering is related to the total cross sections and the...
متن کاملDiffractive Photoproduction of Heavy Vector Mesons
Diffractive vector meson production is described on the one hand within the phenomenological framework based on Regge theory, and on the other hand by perturbative QCD calculations. Light vector mesons in the photoproduction regime (where no hard scale is present) agree well with non-perturbative Regge based descriptions. Perturbative effects are measured in the presence of a hard scale for lig...
متن کاملHeavy Vector Meson Production at Hera
Representing the H1 and ZEUS collaborations Recent results from the HERA experiments H1 and ZEUS on the exclusive production of heavy vector mesons V in ep collisions, i.e. the reaction ep ! eV p, are reviewed. The new measurements 1 include photoproduction of J== at larger photon-proton centre-of-mass energy W than previously, more precise data on J== electroproduction and (2S) photoproduction...

About possible influence of birefringence effect on processes of production (photoproduction, electroproduction) of vector mesons (particles with the spin S ≥ 1) in nuclei Abstract It is shown that birefringence effect influences on production of particles with the spin S ≥ 1 at collisions of high energy particles.

Exclusive vector meson photoproduction, pp → ppV and pp → ppV occurs with significant rates at hadron colliders. The reaction can be used to study the gluon distribution of protons. Vector mesons may be produced with either proton as a target; because of interference between the two production channels, the pT spectra of vector mesons produced in pp and pp collisions are quite different. Becaus...
