Transforming differential equations of multi-loop Feynman integrals into canonical form

Journal of High Energy Physics, 2017
The method of differential equations has been proven to be a powerful tool for the computation of multi-loop Feynman integrals appearing in quantum field theory.

Top-quark pair hadroproduction at NNLO: differential predictions with the MS ¯ $$ \overline{\mathrm{MS}} $$ mass

Journal of High Energy Physics, 2020
We consider top-quark pair production at the LHC within the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme for the renormalisation of the top-quark mass, and we present predictions for total and differential cross sections at next-to-next-to-leading order ...

Multiplicity and Underlying Event in ALICE: as measurements and as tools to probe QCD

, 2018
With the high collision energies at the LHC, the contributions to particle production from hard-QCD processes increase, but it remains dominated by soft-QCD processes.

Precision phenomenology with MCFM

Journal of High Energy Physics, 2019
Without proper control of numerical and methodological errors in theoretical predictions at the per mille level it is not possible to study the effect of input parameters in current hadron-collider measurements at the required precision.

Diphoton production at the LHC: a QCD study up to NNLO

Journal of High Energy Physics, 2018
We consider the production of prompt-photon pairs at the LHC and we report on a study of QCD radiative corrections up to the next-to-next-to-leading order (NNLO). We present a detailed comparison of next-to-leading order (NLO) results obtained within the

Gauge-invariant quark and gluon fields in QCD: dynamics, topology, and the Gribov ambiguity

, 2001
We review the implementation, in a temporal-gauge formulation of QCD, of the non-Abelian Gauss's law and the construction of gauge-invariant gauge and matter fields.

Global QCD Analysis and Collider Phenomenology--CTEQ

, 2007
An overview is given of recent progress on a variety of fronts in the global QCD analysis of the parton structure of the nucleon and its implication for collider phenomenology, carried out by various subgroups of the CTEQ collaboration.

Zγ production at NNLO including anomalous couplings

Journal of High Energy Physics, 2017
In this paper we present a next-to-next-to-leading order (NNLO) QCD calculation of the processes pp → l + l −γ and pp→νν¯γ $$ pp\to \nu \overline{\nu}\gamma $$ that we have implemented in MCFM.
