A detailed investigation of W+c-jet at the LHC
Michał Czakon, Alexander Mitov, Mathieu Pellen +1
State-of-the-art analyses of W+c-jet production at the LHC require precise predictions. In the present work, we study in detail the impact of off-diagonal CKM elements up to next-t…
Revisiting the double-soft asymptotics of one-loop amplitudes in massless QCD
Michał Czakon, Felix Eschment, Tom Schellenberger
We evaluate the one-loop soft current for the emission of two soft gluons or a soft quark-anti-quark pair in massless Quantum Chromodynamics. The results are exact in dimensional r…
NNLO B-fragmentation fits and their application to production and decay at the LHC
Michał Czakon, Terry Generet, Alexander Mitov +1
In this work we derive three sets of non-perturbative fragmentation functions, with uncertainties, for -hadrons, 's and muons resulting from semileptonic decays. All th…
A note on quark and gluon energy-momentum tensors
Taushif Ahmed, Long Chen, Michał Czakon
We discuss the constraints on quark and gluon energy-momentum tensors in QCD that follow from the requirement of Renormalisation-Group invariance of the traces of these operators.…
Infrared-safe flavoured anti- jets
Michal Czakon, Alexander Mitov, Rene Poncelet
Flavour tagging is technically challenging on the experimental side. However, it suffers from a more fundamental problem from the theoretical point of view, in particular when impl…
Complete collection of one-loop triple-collinear splitting operators for dimensionally-regulated QCD
Michał Czakon, Sebastian Sapeta
We provide results for the one-loop triple-collinear color/spin-space splitting operators for the five possible processes, , , , $g \…
