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.

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 ...

A Unified Approach to QCD Phenomenology [PDF]
AIP Conference Proceedings, 1983 The Fock state Have functions of hadrons defined by quantizing quantum chromodynamics at equal time on the light‐cone provides a unifying element in QCD predictions, from low to high momentum transfer. A number of novel QCD effects are reviewed, including heavy quark and higher twist phenomena, initial and final state interactions, direct 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

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.

Color-symmetric superconductivity in a phenomenological QCD model
The European Physical Journal A, 2009 In this paper, we construct a theory of the NJL-type where superconductivity is present, and yet the super-conducting state remains, in the average, color symmetric. This shows that the present approach to color superconductivity is consistent with color singlet-ness.
