Three-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 ...
متن کاملNNLO corrections to 2-jet observables in electron-positron annihilation
I report on a numerical program, which can be used to calculate any infra-red safe twojet observable in electron-positron annihilation to next-to-next-to-leading order in the strong coupling constant αs. The calculation is based on the subtraction method. The result for the two-jet cross section is compared to the literature.
متن کاملAnnihilation to Next-to-leading Order Accuracy *
We discuss the production of two hadrons in e + e − annihilation within the framework of perturbative QCD. The cross section for this process is calculated to next-to-leading order accuracy with a selection of variables that allows the consideration of events where the two hadrons are detected in the same jet. In this configuration we contemplate the possibility that the hadrons come from a dou...
متن کاملNext-to-leading Order Qcd Corrections to Parity-violating 3-jet Observables for Massive Quarks in E + E − Annihilation I Introduction Ii Kinematics and Leading-order Results
In this work we provide all the missing ingredients for calculating parity-violating 3-jet observables in e + e − collisions at next-to-leading order (NLO) including the full quark mass dependence. In particular we give explicit results for the one-loop corrections and for the singular contributions from real emission processes. Our formulae allow for the computation of the NLO 3-jet contributi...
متن کاملElectron - Positron Annihilation into Four Jets at Next - to - Leading Order in as 1
We calculate the rate for e+ eannihilation into four jets at next-to-leading order in perturbative QCD, but omitting terms that are suppressed by one or more powers of l/iV~, where N. is the number of colors. The O(a~) corrections depend strongly on the jet resolution parameter yCut and on the clustering and recombination schemes, and they substantially improve the agreement between theory and ...
