Quarkonium production in high-energy reactions is found to exhibit a behaviour more universal than that expected from velocity scaling. Total rates of quarkonia produced in hadronic interactions as well as Feynmanx and transverse momentum distributions can be described over the full range of accessible energies (15GeV) by two-stage processes. The quarkonium production cross section factors into a process-dependent short-distance part and a single long-distance matrix element. The first part describing the production of a free quark-antiquark pair is the perturbatively calculated subthreshold cross section. The non-perturbative factor turns out to be universal, giving the model great predictive power. Furthermore we estimate the fraction of the heavy-quark cross section leading to quarkonium for both the charm and bottom systems. Finally, we comment on quarkonium photoproduction.a Heisenberg Fellow.

“…The first experimental evidence of the existence of quarks belonging to the third family was obtained in 1977, with the observation of a 9.5 GeV dimuon resonance in 400 GeV proton-nucleus collisions [9] and evidence for a close-by second resonance [10], later followed by a third [11]. Experiments at the DORIS-II electron-positron collider confirmed these narrow resonances and established their interpretation as radial excitations of the bb bound system [12].…”

Minijet production in √ s = 5.5 TeV Pb+Pb collisions at the LHC is expected to produce a gluon-dominated plasma with large initial temperatures and energy densities. We discuss the implications of the high initial temperatures on the screening mass and on the relative suppression of members of the Υ family. We demonstrate that p T -dependence of the Υ ′ /Υ ratio is only expected if a quark-gluon plasma with significant energy density is present, and that the precise dependence of this ratio will strongly constrain the QGP models. We also propose that the p T spectra of the Υ resonances themselves will provide valuable information by comparing these spectra to that of the Z boson, which should not be influenced by plasma production.
