Coefficient functions and open charm production in deep inelastic scattering
It is shown that the problem of double counting in open charm production in DIS can be solved by using the expression for DIS coefficient functions in terms of 2PI diagrams.

متن کاملCharm production in diffractive deep inelastic scattering
The diffractive open charm production is computed in perturbative QCD formalism and in the Regge approach. The results are compared with recent data on charm diffractive structure function measured at DESY-HERA. Our results demonstrate that this observable can be useful to discriminate the QCD dynamics.
متن کاملCharm Production in Deep Inelastic Scattering
Charm quarks are produced copiously in deep inelastic scattering (DIS) at HERA. At sufficiently high photon virtualities, Q, the production of charm quarks constitutes up to 30% of the total cross section [1,2]. Previous measurements of D∗ cross sections [1,2,3,4] indicate that the production of charm quarks in DIS in the range 1 < Q < 600 GeV is consistent with QCD calculations in which charm ...
متن کاملCharm in Deep Inelastic Scattering
We outline the existing descriptions of the charm component of the deep inelastic proton structure function F2. We discuss recent approaches to include charm mass effects in the parton evolution equations and the coefficient functions. Contribution to the Proceedings of the Madrid low x Workshop, June 18-21 1997, Miraflores, Spain Both H1 and ZEUS have used c → D to measure charm production in ...
متن کاملOpen charm production in deep inelastic scatterimz at next - to -
An introduction and overview of charm production in deep inelastic scattering at HERA is given. The existing next-to-leadlng order perturbative QCD calculations are then reviewed, and key results are summarized. Finally, comparisons are made with the most recent HERA data, and unresolved issues are highlighted.
