Inelastic photoproduction

1995

Abstract 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-target photoproduction data and predictions are given for the HERA energy range.

Heavy-quark production in two-photon collisions

1993

Abstract Heavy quarks are copiously produced in two-photon collisions at e + e − colliders. We present the inclusive production rates and the final state distributions of the quarks, including QCD radiative corrections for the leading subprocesses. The results are compared with recent measurements of charmed particle production at PETRA and PEP, and predictions are given for TRISTAN and LEP energies.
