Heavy quark production in photon-nucleon and photon-photon collisions
We discuss several mechanisms of heavy quark production in (real) photon-nucleon and (real) photon (real) photon collisions. In particular we focuse on application of the Saturation Model. We discuss how to generalize the formula from virtual photon proton scattering and analyze threshold effects. We discuss a possibility to measure the cross section for γγ → 2c2c̄. In addition to the main dipol...
متن کاملRemarks on heavy-quark production in photon-nucleon and photon-photon collisions
I discuss mechanisms of heavy quark production in (real) photon-nucleon and (real) photon (real) photon collisions. In particular, I focuse on application of the Saturation Model. In addition to the main dipole-nucleon or dipole-dipole contribution included in recent analyses, I propose how to calculate within the same formalism the hadronic single-resolved contribution to heavy quark productio...

متن کاملHeavy-quark Correlations in Direct Photon-photon Collisions
In two-photon collisions at LEP2 and a future ee linear collider heavy quarks (mainly charm) will be pair-produced rather copiously. The production via direct and resolved photons can be distinguished experimentally via a remnant-jet tag. We study correlations of the heavy quarks at next-to-leading order in QCD in the direct channel, which is free from phenomenological parton densities in the p...
متن کاملHeavy-Quark Correlations in Photon-Hadron Collisions
We describe a next-to-leading-order calculation of the fully exclusive parton cross section at next-to-leading order for the photoproduction of heavy quarks. We use our result to compute quantities of interest for current fixed-target experiments. We discuss heavy-quark total cross sections, distributions, and correlations.
