Simultaneous extraction of and from LHC differential distributions
Amanda M. Cooper-Sarkar, Michal Czakon, Matthew A. Lim +2
We present a joint extraction of the strong coupling and the top-quark pole mass from measurements of top-quark pair production performed by the ATLAS and CMS experimen…
An exploratory study of the impact of CMS double-differential top distributions on the gluon parton distribution function
Michał Czakon, Sayipjamal Dulat, Tie-Jiun Hou +6
LHC data have the potential to provide constraints on the gluon distribution, especially at high , with both ATLAS and CMS performing differential measurements. Recen…
Higher order corrections to spin correlations in top quark pair production at the LHC
Arnd Behring, Michal Czakon, Alexander Mitov +2
We calculate, for the first time, the next-to-next-to leading order (NNLO) QCD corrections to spin correlations in top quark pair production at the LHC. The NNLO corrections play a…
NNLO versus NLO multi-jet merging for top-pair production including electroweak corrections
Michał Czakon, Christian Gütschow, Jonas M. Lindert +6
In this proceedings we compare phenomenological predictions for differential distributions in top-quark pair production at the LHC. In particular we consider NNLO QCD fixed-order p…
Top-quark pair production at complete-NLO accuracy with NNLO+NNLL corrections in QCD
Michal Czakon, Andrea Ferroglia, Alexander Mitov +8
We describe predictions for top-quark pair differential distributions at hadron colliders, which combine state-of-the-art NNLO QCD calculations and NLO electroweak corrections toge…
Beyond the Standard Model Physics at the HL-LHC and HE-LHC
X. Cid Vidal, M. D'Onofrio, P. J. Fox +294
This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in…
Top Quark Pair Production: theory overview
Andrew S. Papanastasiou
In this talk we present the current status of the theoretical description of the production of top-quark pairs at the LHC, detailing recent progress for predictions at the stable-t…
Heavy-flavor parton distributions without heavy-flavor matching prescriptions
Valerio Bertone, Alexandre Glazov, Alexander Mitov +2
We show that the well-known obstacle for working with the zero-mass variable flavor number scheme, namely, the omission of O(1) mass power corrections close to the conventional hea…
Top-quark pair-production and decay at high precision
Jun Gao, Andrew S. Papanastasiou
We present a fully-differential and high-precision calculation of top-quark pair-production and decay at the LHC, providing predictions for observables constructed from top-quark l…
Matched predictions for the cross section at the 13 TeV LHC
Marco Bonvini, Andrew S. Papanastasiou, Frank J. Tackmann
We present up-to-date matched predictions for the inclusive cross section at the LHC at TeV. Using a previously developed method, our predictions consiste…
Off-shell single-top production at NLO matched to parton showers
Rikkert Frederix, Stefano Frixione, Andrew S. Papanastasiou +2
We study the hadroproduction of a pair in association with a light jet, focusing on the dominant -channel contribution and including exactly at the matrix-element level all…
Probing the top-quark width through ratios of resonance contributions of
Stefan Liebler, Gudrid Moortgat-Pick, Andrew S. Papanastasiou
We exploit offshell regions in the process to gain access to the top-quark width. Working at next-to-leading order in QCD we show that carefully…
Resummation and Matching of -quark Mass Effects in Production
Marco Bonvini, Andrew S. Papanastasiou, Frank J. Tackmann
We use a systematic effective field theory setup to derive the production cross section. Our result combines the merits of both fixed 4-flavor and 5-flavor schemes. It…
Renormalization-group improved fully differential cross sections for top pair production

This report summarizes the proceedings of the 2014 Mainz Institute for Theoretical Physics (MITP) scientific program on "High precision fundamental constants at the TeV scale". The…
Single-top -channel production with off-shell and non-resonant effects
A. S. Papanastasiou, R. Frederix, S. Frixione +2
This letter details and discusses the next-to-leading order QCD corrections to -channel electro-weak production, where finite top-width effects are consistently taken…
Finite-width effects in unstable-particle production at hadron colliders
