Determination of the strong coupling constant using matched NNLO+NLLA predictions for hadronic event shapes in e+e- annihilations
G. Dissertori, A. Gehrmann-De Ridder, T. Gehrmann +4
We present a determination of the strong coupling constant from a fit of QCD predictions for six event-shape variables, calculated at next-to-next-to-leading order (NNLO) and match…
Photon - Jet Correlations and Constraints on Fragmentation Functions
Z. Belghobsi, M. Fontannaz, J. -Ph. Guillet +3
We study the production of a large-pT photon in association with a jet in proton-proton collisions. We examine the sensitivity of the jet rapidity distribution to the gluon distrib…
Jet rates in electron-positron annihilation at O(α_s^3) in QCD
A. Gehrmann-De Ridder, T. Gehrmann, E. W. N. Glover +1
We compute production rates for two, three, four and five jets in electron-positron annihilation at the third order in the QCD coupling constant. At this order, three-jet productio…
Sector Decomposition
Gudrun Heinrich
Sector decomposition is a constructive method to isolate divergences from parameter integrals occurring in perturbative quantum field theory. We explain the general algorithm in de…
Event shapes in annhilation at NNLO
A. Gehrmann-De Ridder, T. Gehrmann, E. W. N. Glover +1
We report first results on the calculation of NNLO corrections to event shape distributions in electron-positron annhilation. The corrections are sizeable for all variables, howeve…
Next-to-leading order multi-leg processes for the Large Hadron Collider
T. Binoth, T. Reiter, J. R. Andersen +6
In this talk we discuss recent progress concerning precise predictions for the LHC. We give a status report of three applications of our method to deal with multi-leg one-loop ampl…
