Production of heavy quarks and heavy quarkonia
Uncertainties in the next-to-leading-order calculations of heavyquark (Q) production are investigated. Predictions for total cross sections, single-inclusive distributions of heavy quarks and heavy flavoured hadrons, as well as for QQ̄ correlations, are compared with charm and bottom data. The description of heavy-quarkonium production requires a separation of the short-distance scale of QQ̄ prod...
متن کاملSingle eta production in heavy quarkonia transitions
The η production in the (n, n ′) bottomonium transitions Υ(n) → Υ(n ′)η, is studied in the method used before for dipion heavy quarko-nia transitions. The widths Γ η (n, n ′) are calculated without fitting parameters for n = 2, 3, 4, 5, n ′ = 1.Resulting Γ η (4, 1) is found to be large in agreement with recent data.

Multipole expansion method is shown to be inadequate for large size systems con...
متن کاملHeavy Quarkonia
Recent experimental results on heavy quarkonia spectroscopy and decays are reviewed. In particular, new results are discussed on charmonium spin singlet states, bottomonium D-states, photon and hadronic transitions from heavy quarkonium states, and the unexplained narrow X(3872) state.
متن کاملPhotoproduction of Heavy Quarkonia
We investigate the reaction γp → V p, with V denoting a Φ or a J/Ψ meson, within the scope of perturbative QCD, treating the proton as a quark-diquark system. Our predictions extrapolate the existing forward differential cross-section data into the few-GeV momentum-transfer region. In case of the J/Ψ reasonable results are only obtained by properly taking into account its mass in the perturbati...
