Quarkonia production with the HERA B experiment
نویسنده
چکیده
Abstract. Measurements of the dependence of the J/ψ production cross section on its kinematic variables as well as on the target atomic numbers for 920 GeV/c protons incident on different targets have been made with the HERA B detector. The large collected di-lepton sample allows to study the production ratio of ψ(2S) to J/ψ and of χc to J/ψ. We also report on measurements of the bb and Υ production cross section.

Bottomonium Polarization in Hadroproduction
The polarization of the Υ and χb2 mesons in hadron hadron collisions is considered. It is shown that both states are produced with a noticeable polarization which allows to use forthcoming data of DESY HERA-B and of the RHIC collider experiments to discriminate between the different mechanisms of heavy quarkonia production.

متن کاملHard Photoproduction at HERA
In view of possible photoproduction studies in ultraperipheral heavy-ion collisions at the LHC, we briefly review the present theoretical understanding of photons and hard photoproduction processes at HERA, discussing the production of jets, light and heavy hadrons, quarkonia, and prompt photons. We address in particular the extraction of the strong coupling constant from photon structure funct...
متن کاملAssociated J/ψ + γ Photoproduction as a Probe of the Colour-Octet Mechanism
The associated production of a J/ψ and a photon in photon-hadron collisions is considered, and shown to be a good probe of the presence of colour-octet mediated channels in quarkonia production, as predicted by the factorization approach within NRQCD. Total and differential cross sections for photoproduction at fixed target experiments and at HERA are presented. Associated J/ψ+ γ production at ...
متن کاملQuarkonium Production via Fragmentation: a Review
We review the physics of quarkonium production at high energy colliders, with a specific emphasis on production via fragmentation. We discuss the fragmentation picture for the production of quarkonia at large-pT at the Tevatron and emphasise the importance of the colour-octet components of the quarkonium wave function which are included in the fragmentation functions. Applications of these theo...
متن کاملSingle Polarisation Asymmetries for Quarkonia in Non-relativistic QCD
We find that single spin asymmetries in NRQCD are non-vanishing in general. They are proportional to the imaginary parts of some nonperturbative matrix elements. With statistics of about 10 identified J/ψ’s, or 10 identified χ2, it is possible to measure these imaginary parts even if they are an order of magnitude smaller than the real parts. Such statistics are quite reasonable at polarised HE...
