Top-quark pair production at the LHC: fully differential QCD predictions at NNLO


Catani, Stefano; Devoto, Simone; Grazzini, Massimiliano; Kallweit, Stefan; Mazzitelli, Javier (2019). Top-quark pair production at the LHC: fully differential QCD predictions at NNLO. Journal of High Energy Physics, 2019(7):100.

Abstract

We report on a new fully differential calculation of the next-to-next-to-leading-order (NNLO) QCD radiative corrections to the production of top-quark pairs at hadron colliders. The calculation is performed by using the qT subtraction formalism to handle and cancel infrared singularities in real and virtual contributions. The computation is implemented in the Matrix framework, thereby allowing us to efficiently compute arbitrary infrared-safe observables for stable top quarks. We present NNLO predictions for several single- and double-differential kinematical distributions in pp collisions at the centre-of-mass energy s√=13 TeV, and we compare them with recent LHC data by the CMS collaboration.
