Direct Photon Production at Next-to–Next-to-Leading Order

“…Over the last few years significant progress has been made in the field of NNLO calculations, allowing for the calculation of processes involving one [9][10][11][12][13][14][15] or two [16,17] massless partons in the final state for the first time. One of the developments that has proven very fruitful for computing NNLO corrections is a novel method for regulating the infrared (IR) singular structure known as N -jettiness slicing (or subtraction).…”

Determination of the strong coupling constant $${\varvec{{\alpha _\mathrm{s} (m_\mathrm{Z})}}}$$ in next-to-next-to-leading order QCD using H1 jet cross section measurements

“…Continuous developments enabled the advancement of these calculations [7][8][9][10], and next-to-next-toleading order (NNLO) predictions for jet production in DIS [11,12] and hadron-hadron collisions [13,14] have become available recently. The theoretical uncertainties of the NNLO predictions are substantially reduced compared to those of the NLO predictions.…”

Constraints on the Parton Density Functions of the Proton by Measurements with the ATLAS Detector

“…Although some improvement is seen using such models, it is not sufficient to provide good agreement at NLO. It will be interesting to see to what extent this may also be the case when comparing with the recent predictions of the jet cross sections at next-to-next-to-leading order (NNLO) [11,12].…”
