“…As for the full neutral-current DY, the QCD×QED corrections to the production of a pair of neutrinos have been discussed in ref. [38], and the complete NNLO QCD-EW corrections for a charged lepton pair in the final state have been presented in [39,40]. Considering pole-approximation only for the virtual contributions, the QCD-EW corrections to the charged current DY has been obtained in [41].…”

The analytical expressions of the mixed QCD-EW corrections to on-shell Z boson inclusive production cross section at hadron colliders are presented, together with computational details. The results are given in terms of polylogarithmic functions and elliptic integrals. The impact on the prediction of the Z boson production total cross section is discussed, comparing different proton parton density sets.

“…In this article we explore the technique of generalised series expansions [32], as implemented in the software DiffExp [33], to numerically solve the differential equations for the master integrals. Such a technique would be applicable to two-loop integrals even in the presence of non-polylogarithmic forms, and it has been exploited recently for several processes [34][35][36][37].…”

We compute helicity amplitudes for the one-loop QCD corrections to top-quark pair production analytically in terms of a set of uniformly transcendental master integrals. We provide corrections up to O(ε 2 ) in the dimensional regulator for the first time which are relevant at NNLO. Four independent pentagon integral topologies appear in the complete description of the colour structure for which we provide numerical solutions using canonical form differential equations and the method of generalised power series expansions. Analytic forms of the boundary values are obtained in all cases except one where we find a one-dimensional integral representation.

“…The calculation considers a massive leptonic final state, and features collinear logarithms of the lepton mass. These results, combined with the remaining perturbative contributions, allow the numerical evaluation of the hadron-level cross-section at this perturbative order, as presented in [62].…”

We present the two-loop mixed strong-electroweak virtual corrections to the neutral current Drell-Yan process and we provide, in ancillary files, the explicit formulae of the infrared-subtracted finite remainder. The final state collinear singularities are regularised by the lepton mass. The evaluation of all the relevant Feynman integrals, including those with up to two internal massive lines, has been worked out relying on analytical and semi-analytical techniques, in the case of complex-valued masses.
