Photoproduction of quarkonium in proton-proton and nucleus-nucleus collisions.
We discuss the photoproduction of Upsilon and J/psi at high energy pp, pp, and heavy ion colliders. We predict large rates in pp interactions at the Fermilab Tevatron and in pp and heavy ion interactions at the CERN Large Hadron Collider. The J/psi is also produced copiously at the Relativistic Heavy Ion Collider. These reactions can be used to study the gluon distribution in protons and heavy ...
متن کاملProduction of ω-mesons in proton-proton collisions
The production of ω-mesons in proton-proton collisions for proton incident energies up to 2.2 GeV is investigated within a mesonexchange model of hadronic interactions. We find a large cancellation between the dominant πρω meson-exchange current and nucleonic current contributions. A comparison with preliminary data from SATURNE calls for the inclusion of off-shell form factors at the NNω and π...
متن کاملElectromagnetic interactions in nucleus-nucleus and proton-proton collisions
The strong electromagnetic fields associated with ultra-relativistic protons and nuclei correspond to an equivalent flux of photons. At the future Large Hadron Collider at CERN, the corresponding photon-nucleon center of mass energies will be higher than at any existing accelerator. The experimental and theoretical aspects of particle production in electromagnetic interactions at hadron collide...
متن کاملHeavy Quark Photoproduction in Proton-proton Collisions
We calculate the photoproduction of heavy quarks in proton-proton collisions at RHIC, Tevatron and LHC energies. The integrated cross section and the rapidity distributions for open charm and bottom production are computed employing sound high energy QCD formalisms. For the linear pQCD approaches we consider both the usual collinear factorization and the k⊥factorization formalisms, whereas for ...
متن کاملStrangeness production in proton - proton and proton - nucleus collisions ∗
In these lectures we discuss the investigation of the strange meson production in protonproton (pp) and in proton-nucleus (pA) reactions within an effective Lagrangian model. The kaon production proceeds mainly via the excitations of N(1650), N(1710), and N(1720) resonant intermediate nucleonic states, in the collision of two initial state nucleons. Therefore, the strangeness production is expe...
