The Dipole Formalism for the Calculation of QCD Jet Cross Sections at Next-to-Leading Order
نویسنده
چکیده
In order to make quantitative predictions for jet cross sections in perturbative QCD, it is essential to calculate them to next-to-leading accuracy. This has traditionally been an extremely laborious process. Using a new formalism, imaginatively called the dipole formalism, we are able to construct a completely general algorithm for next-to-leading order calculations of arbitrary jet quantities in arbitrary processes. In this paper we present the basic ideas behind the algorithm and illustrate them with a simple example.

متن کاملA general approach to jet cross sections in QCD
I illustrate a general formalism based upon the subtraction method for the calculation of next-to-leading order QCD cross sections for any number of jets in any type of hard collisions. I discuss the implementation of this formalism in a numerical program which generates partonic kinematical configurations with an appropriate weight, thus allowing the definition of arbitrary jet algorithms and ...

Heavy quark and direct photon production in hadronic collisions are processes of great interest. The discovery of the top has increased efforts in the calculation of heavy quark production cross sections while direct photon production is important for determinations of gluon distributions. Near threshold for the production of the final state in these processes one can resum logarithmic correcti...
متن کاملCalculation of QCD jet cross sections at next - to - leading order
A general method for calculating next-to-leading order cross sections in perturbative QCD is presented. The algorithm is worked out for calculating N -jet cross sections in hadron-hadron collisions. The generalization of the scheme to performing caclulations for other QCD process, such as electron-positron annihilation or in deep inelastic scattering is also straightforward. As an illustration ...
