“…In this proceeding, we discuss Ref. [33], where we have presented the first results for the total inclusive partonic cross section for the process qq → Z + X, including the exact O(αα s ) corrections, with both photon and W /Z boson exchanges. The results are analytic and are expressed in terms of GPLs, but also contain three elliptic MIs, which have been computed with a series expansion around z = 1.…”

“…These non-factorisable O(α s α) terms have been shown [30][31][32] to have a negligible impact on the cross section, allowing to treat effectively Drell-Yan in the (resonant) limit of the decoupling between the production and decay processes, at least for the achieved experimental accuracy. Several steps towards the computation of the (inclusive) initial state QCD×EW corrections have been recently carried out in an analytical way [33][34][35]. The appearance of massive gauge bosons results in extra complications, so it seems natural to start by looking at the case of QED contributions instead.…”

In this work we extend the qT -subtraction formalism, originally developed for QCD corrections, to the case of mixed QCD⊗QED corrections, and apply it to the fully exclusive calculation of the $$ \mathcal{O}\left({\alpha}_s\alpha \right) $$ O α s α contribution to the production of an off-shell Z boson in hadronic collisions. We present explicit results for the subtraction term and the hard factor, therefore providing all the ingredients needed for the application of the formalism up to $$ \mathcal{O}\left({\alpha}_s\alpha \right) $$ O α s α . To study the phenomenological impact we consider the decay of the off-shell Z boson into a pair of neutrinos, and present kinematical distributions for the final-state leptons at LHC energies.

“…NNLO QED as well as QCD×QED corrections to Higgs production in bottom quark annihilation were obtained [29] to estimate the impact of QED radiative corrections. More recently, NNLO EW-QCD effects to single vector boson production were reported in [30,31].…”

We study the infrared (IR) structure of SU(N) × U(1) (QCD × QED) gauge theory with n f quarks and n l leptons within the framework of perturbation theory. In particular, we unravel the IR structure of the form factors and inclusive real emission cross sections that contribute to inclusive production of color neutral states, such as a pair of leptons or single W/Z in Drell-Yan processes and a Higgs boson in bottom quark annihilation, in Large Hadron Collider (LHC) in the threshold limit. Explicit computation of the relevant form factors to third order and the use of Sudakov's K + G equation in SU(N)×U(1) gauge theory demonstrate the universality of the cusp anomalous dimensions (A I , I = q, b). The abelianization rules that relate A I of SU(N) with those from U(1) and SU(N) × U(1) can be used to predict the soft distribution that results from the soft gluon emission subprocesses in the threshold limit. Using the latter and the third order form factors, we can obtain the collinear anomalous dimensions (B I) and the renormalisation constant Z b to third order in perturbation theory. The form factors, the process independent soft distribution functions can be used to predict fixed and resummed inclusive cross sections to third order in couplings and in leading logarithmic approximation respectively.
