Prompt Photon Plus Jet Photoproduction at HERA at Next-to-Leading Order in QCD
The cross section for photoproduction of an isolated prompt photon in association with a jet is studied in Next-to-Leading Order. The kinematics are those appropriate for the DESY ep collider HERA. The effects on the cross section of various experimental cuts including isolation cuts on the photon is examined. Comparisons with the ZEUS preliminary data using two parametrizations of the photon s...
متن کاملDetailed Comparison of Next-to-Leading Order Predictions for Jet Photoproduction at HERA
The precision of new HERA data on jet photoproduction opens up the possibility to discriminate between different models of the photon structure. This requires equally precise theoretical predictions from perturbative QCD calculations. In the past years, next-to-leading order calculations for the photoproduction of jets at HERA have become available. Using the kinematic cuts of recent ZEUS analy...
متن کاملThe two-jet rate in ee at next-to-next-to-leading-logarithmic order
We present the first next-to-next-to-leading logarithmic resummation for the two-jet rate in ee annihilation in the Durham and Cambridge algorithms. The results are obtained by extending the ARES method to observables involving any global, recursively infrared and collinear safe jet algorithm in ee collisions. As opposed to other methods, this approach does not require a factorization theorem f...
متن کاملThree-Jet Production in Electron-Positron Collisions at Next-to-Next-to-Leading Order Accuracy.
We introduce a completely local subtraction method for fully differential predictions at next-to-next-to-leading order (NNLO) accuracy for jet cross sections and use it to compute event shapes in three-jet production in electron-positron collisions. We validate our method on two event shapes, thrust and C parameter, which are already known in the literature at NNLO accuracy and compute for the ...

We present the first next-to-next-to-leading-logarithmic resummation for the two-jet rate in e^{+}e^{-} annihilation in the Durham and Cambridge algorithms. The results are obtained by extending the ares method to observables involving any global, recursively infrared and collinear safe jet algorithm in e^{+}e^{-} collisions. As opposed to other methods, this approach does not require a factori...
