Top-Antitop Production and Decay at Threshold at the LHC in QCD Perturbation Theory
Paolo Nason, Giovanni Pelliccioli, Emanuele Re +1
In this work we consider the production of a top-antitop pair at the LHC when the mass of the pair is relatively near to the nominal threshold, that is to say to twice the top pole…
Spin Correlations in Production and Decay at the LHC in QCD Perturbation Theory
Paolo Nason, Emanuele Re, Luca Rottoli
In this work we consider the QCD predictions for spin correlations in production in hadronic collisions. In view of recent tensions between experimental data and theoret…
On Thrust Resummation Ambiguities in Annihilation into Hadrons
Luca Buonocore, Paolo Nason, Luca Rottoli +1
In shape-variable studies, and in particular for the case of thrust, fixed-order QCD predictions are typically supplemented with the resummation of contributions enhanced…
HOPPET v2 release note
Alexander Karlberg, Paolo Nason, Gavin Salam +2
We document the three main new features in the v2 release series of the HOPPET parton distribution function evolution code, specifically support for NLO QCD evolution in the va…
Fits of from event-shapes in the three-jet region: extension to all energies
Paolo Nason, Giulia Zanderighi
This work is an extension of a previous publication [1] where we fitted the strong coupling together with the non-perturbative parameter from event-shape and jet-shap…
