Subthreshold photoproduction of charm
نویسندگان
چکیده
Charm photoproduction rates off nuclei below the nucleon threshold are estimated using the phenomenologically known structure functions both for x < 1 and x > 1. The rates rapidly fall below the threshold from values ∼10 pb for Pb close to the threshold (at 7.5 GeV) to ∼1pb at 6 GeV.

Heavy Flavor in Photoproduction at HERA
Recent results on charm and beauty photoproduction at HERA are discussed. The perturbative QCD calculations are generally smaller than the measured cross sections, particularly in the forward (proton) direction. The study of charm dijet photoproduction is consistent with a significant contribution of charm excitation processes.
متن کاملHeavy Flavor Production at Hera
Recent results of open charm and beauty production in electron proton scattering at HERA are presented. In photoproduction, the measured cross sections for charm exceed fixed order NLO QCD calculations. Experimental evidence supports the hypothesis that a significant fraction of photoproduction events with charm can be described by resolved photon processes, where the charm quark is a constitue...
متن کاملCharm Photoproduction at Large Transverse Momentum and the Charm Content of the Photon
The charm quark photoproduction at large transverse momentum in the resolved photon interaction via partonic subprocess c(γ)g → cg is studied. It is shown that at HERA energies the contribution of the charm quark excitation in the photon in the inclusive charm production at p⊥ > 5 GeV/c dominates over the other resolved photon contribution via the gluon content of the photon and it is about 30%...
متن کاملHeavy Quarkonium Photoproduction at HERA and Charm Content of the Photon
A study of the J/ψ-meson photoproduction at large transverse momentum at HERA energies via the charm quark excitation in the photon is presented. Based on perturbative QCD, nonrelativistic quark model and photon structure function formalism, our calculation demonstrates that the charm content of the photon may be very important for the J/ψ photoproduction at the large transverse momentum. It is...
متن کاملIntrinsic Charm in Proton and J/ψ Photoproduction at High Energies
Based on a perturbative theory of quantum chromodynamics and non-relativistic quark model, associated J/ψ plus open charm photoproduction on charm quarks in a proton via partonic subprocess γc→ J/ψc is discussed. It is shown that the value and energy dependence of the cross section for such process remarkably depends on the choice of charm distribution function in a proton. In the region of sma...
