Beyond The Colour-Singlet Model For Inelastic J/ψ Photoproduction
Bound-state corrections to J/ψ production from almost real photons are calculated in the colour-singlet model. A systematic, gauge-invariant, theory of hard quarkonium processes is used upto O(v2), where v is the relative velocity of the quarks. The internal structure of the meson is characterised by two parameters, ǫB/M and ∇2φ(0)/M2φ(0), in addition to the usual wavefunction at the origin φ(0...
متن کاملInelastic J== Photoproduction
Inelastic photoproduction of J/ψ particles at high energies is one of the processes to determine the gluon distribution in the nucleon. We have calculated the QCD radiative corrections to the color-singlet model of this reaction. They are large at moderate photon energies, but decrease with increasing energies. The cross section and the J/ψ energy spectrum are compared with the available fixed-...
متن کاملHard Colour Singlet Exchange at the Tevatron
We have performed a detailed phenomenological investigation of the hard colour singlet exchange process which is observed at the Tevatron in events which have a large rapidity gap between outgoing jets. We include the effects of multiple interactions to obtain a prediction for the gap survival factor. Comparing the data on the fraction of gap events with the prediction from BFKL pomeron exchang...
متن کاملInelastic photoproduction of polarised J/ψ
The comparison of J/ψ photoproduction data in the inelastic region with theoretical predictions based on the NRQCD approach has remained somewhat ambiguous and controversial, in particular at large values of the inelasticity variable z. We study the polar and azimuthal decay angular distribution of J/ψ mesons as functions of z and transverse momentum pt. Future measurements of decay angular dis...
متن کاملQCD Corrections to Inelastic J/ψ Photoproduction
We present a complete calculation of the higher-order perturbative QCD corrections to inelastic photoproduction of J/ψ particles. A comprehensive analysis of total cross sections and differential distributions for the energy range of the fixed-target experiments and for inelastic J/ψ photoproduction at HERA is performed. The cross section and the J/ψ energy spectrum are compared with the availa...
