Book Description
We discuss two topics in the production of heavy quarks in deep-inelastic scattering: the next-to-leading order Monte-Carlo HVQDIS and the next-to-leading logarithmic resummation of soft gluon effects, including estimates of next-to-next-to-leading order corrections therefrom.

ISBN: 9812388354
Category : Science
Languages : en
Pages : 377
Book Description
The proceedings of this workshop gather the latest experimental results from HERA and capture new trends in HERA phenomenology. Although the presentations are by experts, they are suitable for both theoreticians and experimentalists. H1 members also cover ZEUS results and vice versa. This volume serves to point out existing discrepancies between experimental data and theoretical predictions and to identify projects to take on in the future.

Charm Production in Deep Inelastic Scattering
Author: Sebastian Klein
Publisher: Springer Science & Business Media
ISBN: 3642232868
Category : Science
Languages : en
Pages : 246
Book Description
The production of heavy quarks in high-energy experiments offers a rich field to study, both experimentally and theoretically. Due to the additional quark mass, the description of these processes in the framework of perturbative QCD is much more demanding than it is for those involving only massless partons. In the last two decades, a large amount of precision data has been collected by the deep inelastic HERA experiment. In order to make full use of these data, a more precise theoretical description of charm quark production in deep inelastic scattering is needed. This work deals with the first calculation of fixed moments of the NNLO heavy flavor corrections to the proton structure function F2 in the limit of a small charm-quark mass. The correct treatment of these terms will allow not only a more precise analysis of the HERA data, but starting from there also a more precise determination of the parton distribution functions and the strong coupling constant, which is an essential input for LHC physics. The complexity of this calculation requires the application and development of technical and mathematical methods, which are also explained here in detail.

Languages : en
Pages : 459
Book Description
Experts on elementary-particle physics, both theorists and experimentalists, met to present their latest results on the various aspects of HERA physics, specifically, the H1 and ZEUS collaborations at HERA and the collaborations at LEP and the Tevatron were presented. The topics included: proton structure function; polarized "ep" scattering; final states in deep-inelastic scattering (DIS), with special emphasis on jet production at low x, power corrections in DIS, soft particle production, and instanton effects; photon structure function; photoproduction of jets and hadrons; heavy-flavour and charmonium production; elastic and diffractive ep scattering; and new physics at HERA.

Pages : 996
Book Description
These proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (QCD) studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in lepton-proton scattering.
